Oxygen is essential for life and supports combustion. While oxygen inhalation provides benefits, it also poses hazards and toxic effects if misused. There are several oxygen delivery systems to consider for patients, including compressed gas cylinders, liquid oxygen containers, and oxygen concentrators. When considering oxygen therapy for a patient, it is important to evaluate indications like documented hypoxemia, risks like oxygen toxicity, and how the therapy works via oxygen transport and exchange through hemoglobin binding in the blood and tissues. Proper patient interfaces like nasal prongs or simple face masks are also important to achieve the target oxygen saturation levels.

Oxygen therapy involves the administration of oxygen to maintain adequate tissue oxygenation levels and minimize workload on the cardiopulmonary system. Oxygen is indicated when a patient has documented hypoxemia with oxygen saturation below 90% or a partial pressure of oxygen below 60 mmHg. Various oxygen delivery systems can be used including nasal cannulas, face masks, Venturi masks, and non-rebreather masks to provide different concentrations of oxygen from 24-100% at flow rates of 2-10 LPM. Potential complications of oxygen therapy include oxygen toxicity, depression of ventilation, retinopathy of prematurity, absorption atelectasis, and fire hazards.

Oxygen delivery system
Oxygen delivery systemOxygen delivery system
Oxygen delivery system

An oxygen delivery system administers oxygen to increase arterial oxygenation. Systems are classified as low-flow or variable-performance devices, and high-flow or fixed-performance devices. Low-flow devices include nasal cannulas and masks, which provide supplemental oxygen. High-flow devices like venturi masks, partial rebreather masks, and non-rebreather masks meet inspiratory demands and generate accurate oxygen concentrations. At home, oxygen is delivered via cylinders or concentrators, which remove nitrogen from room air to produce oxygen.

Session III: Oxygen Storage and Delivery Devices
Oxygen Storage Sources
 Liquid oxygen is stored, shipped, and handled in several types of containers,
depending upon the quantity required
 The types of containers in use include cryogenic liquid cylinder/ DURA cylinder, and
cryogenic storage tank
 Storage quantities vary from a few litres to many thousands of litres (In India IS
7396:2017 is followed)
 Since heat leak is always present, vaporization takes place continuously
 Rates of vaporization vary, depending on the design of the container, external
temperatures and the volume of stored product
 Containers are designed and manufactured according to the applicable codes and
specifications for the temperatures and pressures involved
LIQUID OXYGEN CONTAINERS
Liquid oxygen is a cryogenic liquid,
pale blue in colour with a has a
boiling point of –297°F (–183°C).
It is a compressed form of oxygen,
required to be stored in the
vacuum insulated tank much
below -200°C, to ensure that the
oxygen remains in the liquid form.
CRYOGENIC LIQUID
CYLINDERS
(DURA CYLINDER)
• Cryogenic liquid cylinders are insulated, vacuum-jacketed
pressure vessel
• They are equipped with pressure relief valves and
rupture disks to protect the cylinders from pressure
buildup.
• Liquid containers operate at pressures in the range of
100 psig to 350 psig (24 atm) and have capacities
between 80 and 450 liters of liquid
• Oxygen may be withdrawn as a gas by passing liquid
through an internal vaporizer or as a liquid under its own
vapor pressure

CRYOGENIC STORAGE TANKS
• Customer installations generally include a tank, vaporizer,
and pressure control manifold.
• Tanks are generally cylindrical in shape and are mounted in
fixed locations as stationary vessels or on railcar or truck
chassis for easy transportation.
• All tanks are powder- and vacuum-insulated in the annular
space and equipped with various valves to control product
fill, pressure buildup, pressure-relief, product withdrawal,
and tank vacuum.
• Tanks are designed to national and international
specifications for the pressures and temperatures involved.
LMO- PROS & CONS
Pros
Liquid oxygen can be stored in a portable tank and connected
to a Central pipeline.
Liquid oxygen is highly concentrated, so more oxygen can be
stored in a smaller tank and ensure continuous supply at high
pressure.
Most cost-effective system for larger facilities.
Cons
Liquid oxygen cannot be stored for prolong time because it will
vaporize (evaporate) and build-up pressure inside storage tank.
The tank's content must be consumed and refilled often,
requiring the scheduling of deliveries.
The system need PESO license compliance.
GASEOUS OXYGEN
CYLINDERS
• Oxygen gas can be compressed and stored in cylinders.
• These cylinders are filled at a gas manufacturing plant, either via
a cryogenic distillation/ASUs in liquid oxygen form or a process
known as pressure swing adsorption (PSA) in gaseous oxygen
form or by an LMO-based re-filler and transported to health
facilities to be connected to manifold systems (groups of
cylinders linked in parallel) that are piped to areas of the health
facility; or cylinders can be used directly within patient areas.
• Cylinders do not require electricity, but they do require several
accessories and fittings to deliver oxygen, such as pressure
gauges, regulators, flowmeters, and, in some cases, humidifiers.
• Cylinders also require periodic maintenance, commonly provided
by gas suppliers at the point of refilling.
OXYGEN CYLINDER – PROS AND CONS
Pros
• Installation does not need
permission from any authority
like Petroleum and Explosives
Safety Organization (PESO).
• Space accommodating as
construction is long and linear.
• Easy setup, can also be used
bedside without medical gas
pipe system.
Cons
• Recommended as primary
source for small size hospital
up to 30 beds.
• Not recommended (specially in
current pandemic) as primary
source to ICU's.
• Erratic supply chain.
• Chances of carrying infection.

CYLINDER NAMING & SIZING
• Oxygen cylinders are of different sizes.
• Cylinder sizes for medical gases are named alphabetically, unlike
industrial cylinders which are numbered.
• In India most commonly used cylinders are D type (Jumbo) and B
type (Portable) cylinders which contains gaseous oxygen. Dura
cylinders with liquid oxygen are also used in the region.
• Cylinders are fitted with customized valves (either pin index or
bullnose type) that are opened with valve keys, and with valve
guards for safety.
• The Pin Index Safety System (PISS) is designed to ensure the
correct gas is connected to the regulator or other equipment.
• The arrangement of the pins is unique for each gas, and the
positions of the holes on the cylinder valve must correspond with
the pins to prevent the use of the wrong gas.
• Some cylinders have built-in, integral pressure regulators, which
do not require a separate pressure regulator to be fitted to the
cylinder valve before use.
MEDICAL GAS PIPELINE SYSTEM
FUNDAMENTAL PRINCIPLES
• Standards
Designed as per IS 7396, to withstand the pressure at
every different section of the oxygen piping system
• Color
Oxygen pipeline in India is covered in White paint
• Pressure
Near the LMO plant :>15 bars
Wards and zones : > 5 - 7 bars
General delivery : 4-5 bars
MEDICAL GAS PIPELINE SYSTEM
FUNDAMENTAL PRINCIPLES
• Working
Oxygen pipeline system should gradually taper.
Its diameter should systematically reduce from the oxygen
plant to the delivery point
•Construction
Divided the pipeline system into different zones
Have pressure gauges to show pressure in the zones
Have a master alarm and zonal alarms if there is a drop in
pressure
COLOUR CODING FOR GASES
IN MGPS
• The international standard for the colour coding of gas pipeline is
ISO 32: 1977 Gas pipelines for medical use – Marking for
identification of content.
• According to the ISO standard, oxygen should be labelled as white.
• The figure shows differences in gas pipeline colour coding
between ISO and US standards.

time who understands the entire oxygen pipeline layout
Every ward or every zone should have zone or ward wise
drawings of the MGPS with clear indication of pressure
settings and valve positions
There should be display of the entire oxygen pipeline
layout with pressure setting and the valve positions at
centrally accessible places in hospitals
Oxygen Delivery to Patients
OXYGEN CONCENTRATORS- PATIENT
DELIVERY CONSUMABLES & ACCESSORIES
Patient Delivery Accessories
To deliver oxygen from the concentrator to the patient, oxygen outlet
adaptors and oxygen delivery tubing are necessary in addition to replaceable
nasal prongs and/or catheters.
Accessories to divide flow to multiple patients
•Flow rate of delivered oxygen must be continuously adjustable by the user
•Necessary because oxygen flow needs require adjustment over the course of
treatment, particularly important for premature newborns in whom excessive
oxygen therapy causes harm
•Patients are started at different flow rates depending on their age, clinical
condition and the type of breathing device used

The document provides information about the nervous system. It discusses that the brain has two hemispheres and is made up of different areas like the cortex, corpus callosum, and cerebellum. The nervous system allows the brain to quickly send messages to the body. It is divided into the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS). The PNS has two main divisions of sensory and motor. Messages travel from the PNS to the brain and back very quickly, up to 150 meters per second. Reflexes provide an even faster response that bypasses the brain through pathways in the spinal cord.

Options for dividing flow to multiple patients-
Some concentrators have two built-in flowmeters, with two corresponding oxygen outlets, to treat two patients
simultaneously.
This avoids the need for additional user assembly but is limited to a maximum of two patients that can be
treated at the same time.
Only some concentrators designated as paediatric have built-in flowmeters capable of titrating oxygen to very
low flows (0.1–0.2 LPM).
Flowmeter stands consisting of from two to five mounted meters can be used.
This has advantage of being more familiar to clinical staff who are used to using flowmeters on cylinders and
allows precise titration of flow to each individual patient (including down to 0.1 LPM).
• A four-way flow splitter assembly has been used as
a method to split flow.
• It consists of a four-way flow splitter block, nozzles
for 0.5, 1 and 2 LPM and blanking plugs.
• Flow splitters are less preferred than flowmeter
stands or built-in paediatric flowmeters, since the
corresponding blanking plugs are very easily lost or
misplaced.
• Flow splitters use nozzles that deliver oxygen at a
single fixed rate.

They make diagnoses based on factors like hereditary conditions, exposure to toxins or infections, and signs of issues. Pulmonologists may order various tests and treat diseases affecting the lungs and breathing.

◦ Oxygen humidifiers are medical devices that can be
integrated into oxygen delivery systems to humidify
supplemental oxygen.
◦ Humidification is not necessary when oxygen is delivered at
relatively low flow rates through nasal prongs or nasal
catheters
◦ When oxygen is delivered at higher-than-standard flow rates,
or when methods of oxygen delivery bypass the nose, such
as when nasopharyngeal catheters are used, humidification
is needed – especially when cold oxygen is delivered from a
cylinder.
HUMIDIFIERS
There are various types of humidifiers, and their
designs differ in how they apply three main
principles :
1. Temperature: As the temperature of gas
increases, its ability to hold water vapour
increases.
2. Surface area: There is more opportunity for
evaporation to occur due to greater surface area
of contact between water and gas.
3. Time of contact: There is more opportunity for
evaporation to occur when a gas remains in
contact with water for long duration.
TYPES OF HUMIDIFIERS
Bubble humidifier – Non heated (reusable) Bubble humidifier – Non heated (single use) Bubble humidifier – heated
Description A reusable bottle that reduces the dryness of
oxygen by bubbling the gas through distilled water (or
water that has been boiled and cooled) at room
temperature.
A single-use bottle that reduces the dryness of
oxygen by bubbling the gas through distilled water at room
temperature.
A device consisting of a heat source and a humidification
chamber whereby the built-in heater warms the water in
the chamber to add moisture to the airstream as it passes
over the surface.
Merits Simple.
No power required.
Low cost.
Reusable.
Simple.
No power required.
Low cost.
Reusable.
Adjustable heat for more or less moisture.
More efficient at humidifying gas.
Drawbacks High risk of contamination (reduced by changing the water
frequently)
Decontamination required

This document provides an overview of the nasal cavity, including its parts, boundaries, blood supply, nerve supply and applied aspects. It discusses the vestibule, nasal cavity proper, roof, floor and septum of the nasal cavity in detail. The septum has bony, cartilaginous and membranous parts. It receives its blood supply from various arteries and drains into facial and pterygoid veins. The septum is innervated by branches of various cranial nerves. Applied aspects of the nasal septum include its role in nasal obstruction and importance of preserving the septal cartilage.

The neck is divided into anterior and posterior triangles by the sternocleidomastoid muscle. The posterior triangle contains the occipital and supraclavicular triangles and structures like lymph nodes, nerves and blood vessels. The anterior triangle is bounded by the mandible, sternocleidomastoid muscle and midline. It contains the thyroid gland, strap muscles that attach to the hyoid bone and are divided into suprahyoid and infrahyoid groups. The anterior triangle also contains the carotid artery and structures in subdivided areas like the carotid triangle.

◦ Delivers fixed concentration of oxygen
◦ The size of the constriction determines the final concentration of
oxygen for a given gas flow
◦ As forward flow of inspired gas increases, the lateral pressure
adjacent and perpendicular to the vector of flow decreases,
resulting in entrainment of gas.
◦ The smaller the orifice is, the greater the negative pressure
generated, so the more ambient air entrained, the lower the FiO2
◦ FiO2 can be 0.24, 0.28, 0.31, 0.35, 0.4, 0.6
◦ Because of the high fresh gas flow rate, the exhaled gases are
rapidly flushed from the mask, via its holes.
◦ These masks are recommended when a fixed oxygen concentration
is desired in patients whose ventilation is dependent on the
hypoxic drive.

o Can be used for low FiO2 also
o Helps in deciding whether the oxygen
requirement is increasing or decreasing
• Disadvantages:
o Uncomfortable
o Expensive (400-600)
o Cannot deliver high FiO2
o Interfere with eating and drinking
◦ Delivers heated and humidified oxygen via special
devices (e.g., Vapotherm)
◦ Rates up to 8 L/min in infants and up to 40 L/min in
children and adults
◦ High flow washes out cardon dioxide in anatomical
dead space
◦ Creates positive nasopharyngeal pressure
◦ FiO2 remains relatively constant
◦ Because gas is generally warmed to 37°C and
completely humidified, mucociliary functions remain
good and little discomfort is reported

Oxygen Supply Devices
CLEANING AND DISINFECTION
OF RESPIRATORY EQUIPMENT
• Equipment used for respiratory therapy is considered
semi critical; such items should be cleaned and then
receive at least high-level disinfection between patients.
• Chemical germicides used for high-level disinfection
include
• Glutaraldehyde-based formulations (2%)
• Stabilized hydrogen peroxide (6%)
• Peracetic acid (variable concentrations, but ≤ 1% is
sporicidal)
• Sodium hypochlorite (5.25%, diluted to 1000 ppm available
chlorine – 1:50 dilution)
STEPS FOR CLEANING AND DISINFECTION OF
PLASTIC PIECES OF RESPIRATORY EQUIPMENT
Step-1: Wash the equipment with soap (e.g., liquid
dish soap) and clean water.
Step-2: Rinse the equipment completely with
clean water.
Step-3: Disinfect the equipment to inactivate any
remaining pathogens: There are several ways to
disinfect equipment, Safe methods of disinfection
include
Heat for heat-resistant equipment that can withstand high
temperature (e.g., 80 °C); such equipment can be disinfected using a
washer–disinfector.
If a washer or pasteurizer is not available, use a high-end or
commercial dishwasher with a “sanitize” feature that can reach 70 °C.
For plastic equipment that may not tolerate 80 °C and for equipment
that may be damaged by boiling, or in the absence of the equipment
described above, use chemical disinfection (e.g., soak in 1:100 sodium
hypochlorite solution for 30 minutes).

DISPOSABLE EQUIPMENT
Disposable equipment will be changed in the following manner:
• Visibly stained or soiled/ mechanically malfunctioning - Adult ventilator circuits and BiPAP or CPAP circuits,
Resuscitation Bags, other equipment's.
• Changed daily- Oral care devices (i.e., Yankauer and tubing) on all ventilator patients, Suction canisters, Oxygen
masks, nasal cannulas, and oxygen tubing are single patient use.
• As needed-
o Clear nipple adapters (Christmas trees) on flowmeters are reusable and will be wiped down, after a patient’s
hospital stay, by germicidal disposable wipes.
o Properly discard Disposable items after use.
o Periodically drain and discard any condensate that collects in the tubing of the mechanical ventilator, taking
precautions not to allow condensate to drain toward the patient.

NON-DISPOSABLE EQUIPMENT
Small instruments/equipment will be processed in Central
Supply:
• Following patient use, items will be washed with an
approved detergent and warm water.
• Scrubbing will be performed beneath the surface of the
water in order to help prevent the aerosolization of
pathogens and free of secretions, pus, blood, other debris.
• If required soak the equipment for two hours in detergent
and warm water. Towel/air dried for 24 hrs.
• For sterilization follow a) steam under pressure b) the Sterrad
unit (hydrogen peroxide) c) Steris (peracetic acid) depending
on the material contents of the equipment and as per
Central Service recommendations.
• Appropriate personal protective equipment to be worn.
Large equipment cleaning/disinfection like mechanical ventilator:
• Wipe down the controls and entire outside of the equipment
with a compatible disinfectant (e.g. sodium hypochlorite
solution of 0.05% or 500 ppm for non-metal surfaces).
• Disinfect tubing using sodium hypochlorite solution of 0.1% or
1000 ppm, ensuring that the entire lumen of the tubing is
flushed.
• As required expiratory side tubing should be disassembled and
clean with a detergent, rinse, and then do high-level disinfection
or sterilization.
• Bacterial and viral filters are recommended on exhalation valves
when using for a patient care (ARI).
• Only in necessary clean respiratory and pressure lines.

Oxygen Wastage
FREQUENCY OF INAPPROPRIATE OXYGEN USE
WHY IS THERE SO MUCH MISUSE OF OXYGEN?
• Oxygen is safe to use
• Easily available in hospital
• Availability is considered free of cost
• No regulations by higher authorities
• No need for permission of any doctor or nursing staff before rotating the knob
Oxygen is considered a gas, not a drug ‼
Myths about oxgen ‼
BARRIERS TO OPTIMAL OXYGEN USAGE
Where Are We Going Wrong??

Recommended for you

FACTORS LEADING TO MISUSE OF OXYGEN
Lack of physician orders on use of oxygen
• Need for oxygen therapy
• Dose of oxygen (flow of O2, FiO2)
• Route of administration (Nasal prongs, face mask, H3FNC, O2 by hood or ventilator)
• Period of administration (Continous, intermittent or nocturnal)
• Targets of oxygen saturation
• Not reviewing oxygen orders regularly
FACTORS LEADING TO MISUSE OF OXYGEN
Nursing staff
• Lack of awareness of side effects of oxygen among healthcare workers and staff
• Staff time constraints
• Difficulties with changing long established behaviours
• Lack of enthusiasm by senior clinical staff
• Communication difficulties between doctors and nurses
• Lack of full time staff/ Rapid staff turnover
FACTORS LEADING TO MISUSE OF OXYGEN
• Lack of designated space and place for prescribing oxygen
• Notion that all sick patients need oxygen
• Higher targets of SpO2
• Patient transferred from other ward with oxygen therapy in situ
• Knowledge practice gap
• Delay in weaning from oxygen
FACTORS LEADING TO MISUSE OF OXYGEN
Delivery devices
• Incorrect choice of oxygen delivery devices
• Inappropriately worn oxygen delivery devices
• Non availability of proper oxygen delivery devices at all the places
• Non avalability of oxygen blenders to titrate FiO2
• Lack of knowledge about delivery devices

Recommended for you

FACTORS LEADING TO MISUSE OF OXYGEN
Administration
• No quality check on oxygen usage
• No proper institutional guidelines
• Lack of education of healthcare staff about proper usage of oxygen
• No oxygen audit
20211222-Module_2.1-Training_on_Rational_and_Hygenic_Use_of_Oxygen-OD-_USAID_RISE.pptx
FACTORS LEADING TO WASTAGE OF OXYGEN
• Inappropraitely increasing oxygen flow
o Suctioning
o Nebulisation
o Cardio pulmonary resuscitation
o Transport
• Keeping FiO2 to 100% after resuscitation without monitoring SpO2
• Often forgets to close the flowmeter once use is completed
CONSEQUENCES OF IRRATIONAL USE OF OXYGEN

Side Effects Of Oxygen...
Is it so???
SIDE EFFECTS OF OXYGEN THERAPY
• Dryness of mucosa due to high flows
• Elevated PaO2 or hyperoxemia: Increased risk of
o Reactive oxygen species
o Absorption atelectasis in poorly ventilated areas
o Retinopathy of prematurity in newborns
o Risk of infection
o Mortality
o Increased hospital stay
• Coronary vasoconstriction - worsening of Myocardial Infarction
• Reperfusion injury
• Increase in infarct size
• Worsening of stroke
• False reassurance to the staff
• Hypercapnia in patients with type 2 respiratory failure
SIDE EFFECTS OF OXYGEN THERAPY
• Shortage of oxygen supply for the most needed person
• Increased cost of treatment
• Deaths due to hypoxemia

HOW TO PREVENT MISUSE OF OXYGEN ?

Recommended for you

ASSESSMENT
• Assess patient thoroughly
• Dyspnea is not the sign of oxygen insufficiency
• Consider other causes also
o Metabolic acidosis
o Anxiety
o Pain
PRESCRIPTION
• Proper prescription of oxygen by doctors
• Document target saturations as per patient condition
o 94-98% for most acutely sick patients
o 88-92% for patients at risk of hypercapnic respiratory failure
• Proper recording of instructions over nursing chart
ADMINISTRATION OF OXYGEN
• Oxygen should be administered by trained nursing staff
• Proper selection of oxygen device
• Ensure adequate fit to avoid leakage
• Adjust flow rate to achieve target saturation range
• Use of closed suctioning device to prevent de-recruitment

ADMINISTRATION OF OXYGEN

Recommended for you

SELECTION OF OXYGEN DEVICE
Depends on
• Age of the patient
• Oxygen requirements/therapeutic goals
• Patient tolerance to selected interface
• Need for humidification
MONITORING
• Continous monitoring of SpO2 using pulse oximetry
• Pulse oximeter should be available wherever oxygen is used
• Titrate FiO2 and flow of oxygen carefully based on SpO2
• Record SpO2 on patient chart along with other vital signs
• Educate patient about the importance of proper delivery of oxygen
• Monitoring of arterial blood gas wherever indicated
RECOMMENDATIONS FOR ABG MONITORING
• All critically sick patients
• Severe hypoxemia (SpO2 less than 94%)
• Deteriorating saturation or increasing oxygen demand
• Type 2 respiratory failure
• Unreliable oximeter signal e.g - due to poor circulation
• Dyspnea with risk of metabolic acidosis e.g – Renal faliure, diabetes
PROPER GUIDELINES
• Formulate & implement local oxygen policy as per the recent guidelines
• Introduce standard oxygen prescribing system
• Clearly delineating section on drug chart for prescription of oxygen orders
• Dedicated oxygen order charts
• Standarise bedside documentation of oxygen administration

Recommended for you

POLICY MAKERS
• Regular audits and QI check on proper usage of oxygen
• Regular training of doctors, nurse and healthcare professionals
• Regular email notification for dissemination of information
• Informational posters
• Nurse facilitated reminder system
• Address the perception of clinicians
TREATMENT ALGORITHM FOR EMERGENCY
Protocol for use of oxygen in ER should be made
WEANING
• Formulate oxygen-weaning protocols and guidelines
• Follow the proper steps of weaning protocol to improve the patient outcome
• Start titration of oxygen once SpO2 has reached the ordered weaning parameters
• Weaning frequency, set goals and alarms should be prescribed by a physician
• Strike off oxygen from the drug chart when it is not needed
• Consider other etiologies if there is difficulty in weaning from oxygen
o Low hemoglobin, fluid overload
o Lung collapse

MEDICAL OXYGEN 8 ● Medical oxygen is high purity oxygen that is used for medical treatments and is developed for use in the human body. ● Oxygen is an essential medicine used to care for patients at all levels of the healthcare system, including in surgery, trauma, heart failure, asthma, pneumonia and maternal and childcare. ● Oxygen is the most important and essential of the drugs for saving the lives of Covid-19 patients. ● The COVID-19 pandemic has accelerated global demand for oxygen and made the delivery of oxygen supplies more urgent than ever.
  • 9. MEDICAL GRADE OXYGEN An essential medicine required at all levels of the health care system Only high quality, medical- grade oxygen should be given to patients Oxygen of a minimum 90% purity and free from any contamination Oxygen is not a flammable gas, but it easily supports combustion Some fuels, such as oil and grease, burn almost explosively when combined with oxygen Materials flammable in air will burn vigorously in oxygen
  • 10. MEDICAL OXYGEN 10 ● Usually accomplished by a large storage system of liquid oxygen (minus 180 degree Celsius) at the hospital which is evaporated into gaseous by vaporized oxygen supply, pressures are usually around 345– 380 kPa (50.0–55.1 psi) ● The gaseous oxygen is stored in the cylinders at 2000 psi with a pressure regulator that allows to reduce the pressure to 50 psi to the patient.

  • 17. Session III: Oxygen Storage and Delivery Devices
  • 19.  Liquid oxygen is stored, shipped, and handled in several types of containers, depending upon the quantity required  The types of containers in use include cryogenic liquid cylinder/ DURA cylinder, and cryogenic storage tank  Storage quantities vary from a few litres to many thousands of litres (In India IS 7396:2017 is followed)  Since heat leak is always present, vaporization takes place continuously  Rates of vaporization vary, depending on the design of the container, external temperatures and the volume of stored product  Containers are designed and manufactured according to the applicable codes and specifications for the temperatures and pressures involved LIQUID OXYGEN CONTAINERS Liquid oxygen is a cryogenic liquid, pale blue in colour with a has a boiling point of –297°F (–183°C). It is a compressed form of oxygen, required to be stored in the vacuum insulated tank much below -200°C, to ensure that the oxygen remains in the liquid form.
  • 20. CRYOGENIC LIQUID CYLINDERS (DURA CYLINDER) • Cryogenic liquid cylinders are insulated, vacuum-jacketed pressure vessel • They are equipped with pressure relief valves and rupture disks to protect the cylinders from pressure buildup. • Liquid containers operate at pressures in the range of 100 psig to 350 psig (24 atm) and have capacities between 80 and 450 liters of liquid • Oxygen may be withdrawn as a gas by passing liquid through an internal vaporizer or as a liquid under its own vapor pressure
  • 21. CRYOGENIC STORAGE TANKS • Customer installations generally include a tank, vaporizer, and pressure control manifold. • Tanks are generally cylindrical in shape and are mounted in fixed locations as stationary vessels or on railcar or truck chassis for easy transportation. • All tanks are powder- and vacuum-insulated in the annular space and equipped with various valves to control product fill, pressure buildup, pressure-relief, product withdrawal, and tank vacuum. • Tanks are designed to national and international specifications for the pressures and temperatures involved.
  • 22. LMO- PROS & CONS Pros Liquid oxygen can be stored in a portable tank and connected to a Central pipeline. Liquid oxygen is highly concentrated, so more oxygen can be stored in a smaller tank and ensure continuous supply at high pressure. Most cost-effective system for larger facilities. Cons Liquid oxygen cannot be stored for prolong time because it will vaporize (evaporate) and build-up pressure inside storage tank. The tank's content must be consumed and refilled often, requiring the scheduling of deliveries. The system need PESO license compliance.
  • 23. GASEOUS OXYGEN CYLINDERS • Oxygen gas can be compressed and stored in cylinders. • These cylinders are filled at a gas manufacturing plant, either via a cryogenic distillation/ASUs in liquid oxygen form or a process known as pressure swing adsorption (PSA) in gaseous oxygen form or by an LMO-based re-filler and transported to health facilities to be connected to manifold systems (groups of cylinders linked in parallel) that are piped to areas of the health facility; or cylinders can be used directly within patient areas. • Cylinders do not require electricity, but they do require several accessories and fittings to deliver oxygen, such as pressure gauges, regulators, flowmeters, and, in some cases, humidifiers. • Cylinders also require periodic maintenance, commonly provided by gas suppliers at the point of refilling.
  • 24. OXYGEN CYLINDER – PROS AND CONS Pros • Installation does not need permission from any authority like Petroleum and Explosives Safety Organization (PESO). • Space accommodating as construction is long and linear. • Easy setup, can also be used bedside without medical gas pipe system. Cons • Recommended as primary source for small size hospital up to 30 beds. • Not recommended (specially in current pandemic) as primary source to ICU's. • Erratic supply chain. • Chances of carrying infection.
  • 25. B-Type Small Medical Oxygen Cylinder (1.5 CU.M.) • B-type high pressure seamless cylinder for medical oxygen gas, cylinder is ISI marked conforming to IS:7285 part 2, certified by the Bureau of Indian Standards (BIS) and approved by the chief controller of explosive (CCOE) Government of India. • Cylinder made from manganese steel. • 10.2 ltr. Water capacity (40 cu.ft.). • Valve made of brass and chrome plated. • Working pressure 150 kg. F/cm at 15 deg. C. • Hydraulic test pressure 250 kg. F/cm . • Colour code of the cylinder should be as per IS: 3933- 1966 with updating till date. • Filled with medical oxygen gas of medical grade. • Matching key cum spanner to release oxygen for each cylinder separately. • Minimum two years guarantee for cylinder. OXYGEN CYLINDER TYPE B & D D-Type Jumbo Medical Oxygen cylinder (7 CU.F.M.) • Cylinder made from manganese steel. • 46.7 Ltr. water capacity (220 CU.FT.). • Valve made of brass and chrome plated. • Working pressure 150 Kg. f/cm at 15 deg. C. • Hydraulic test pressure 250 Kg. f/cm . • Filled with medical oxygen gas of medical grade. • Matching key cum spanner to release oxygen for each cylinder separately. • Minimum two years guarantee for cylinder. B D
  • 26. CYLINDER LABELLING • Medical gas cylinders are required to be labelled, as the primary means of identifying the contents of the cylinder. The colour of the cylinder is only a guide. • Labels for gas cylinders can be reduced in size and shape to the dimensions specified in ISO 7225 – Gas cylinders – Precautionary labels. • The figure is an example of a typical label.
  • 27. • Diamond hazard label: displaying the primary hazard with additional hazard labels displaying any subsidiary hazards. These labels will display the dangerous goods classification number. • UN number: preceded by the letters UN. The UN number is a number assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods. The UN number for compressed oxygen is UN 1072. • Proper shipping name. • Product name (may be omitted if the proper shipping name is identical). • Signal word, hazard and precautionary statements. • EC number (if applicable). • Package size and pressure. • Company name. • Address of the gas company. • Additional company information. • Contact telephone number.
  • 28. OXYGEN CYLINDER TYPES Cylinders type (Gaseous Medical Oxygen) Dura Cylinder (Liquid Medical Oxygen)
  • 29. CYLINDER NAMING & SIZING • Oxygen cylinders are of different sizes. • Cylinder sizes for medical gases are named alphabetically, unlike industrial cylinders which are numbered. • In India most commonly used cylinders are D type (Jumbo) and B type (Portable) cylinders which contains gaseous oxygen. Dura cylinders with liquid oxygen are also used in the region. • Cylinders are fitted with customized valves (either pin index or bullnose type) that are opened with valve keys, and with valve guards for safety. • The Pin Index Safety System (PISS) is designed to ensure the correct gas is connected to the regulator or other equipment. • The arrangement of the pins is unique for each gas, and the positions of the holes on the cylinder valve must correspond with the pins to prevent the use of the wrong gas. • Some cylinders have built-in, integral pressure regulators, which do not require a separate pressure regulator to be fitted to the cylinder valve before use.
  • 30. MEDICAL GAS PIPELINE SYSTEM FUNDAMENTAL PRINCIPLES • Standards Designed as per IS 7396, to withstand the pressure at every different section of the oxygen piping system • Color Oxygen pipeline in India is covered in White paint • Pressure Near the LMO plant :>15 bars Wards and zones : > 5 - 7 bars General delivery : 4-5 bars
  • 31. MEDICAL GAS PIPELINE SYSTEM FUNDAMENTAL PRINCIPLES • Working Oxygen pipeline system should gradually taper. Its diameter should systematically reduce from the oxygen plant to the delivery point •Construction Divided the pipeline system into different zones Have pressure gauges to show pressure in the zones Have a master alarm and zonal alarms if there is a drop in pressure
  • 32. COLOUR CODING FOR GASES IN MGPS • The international standard for the colour coding of gas pipeline is ISO 32: 1977 Gas pipelines for medical use – Marking for identification of content. • According to the ISO standard, oxygen should be labelled as white. • The figure shows differences in gas pipeline colour coding between ISO and US standards.
  • 33. WORKING OF MANIFOLD • Jumbo manifold system has two banks and one reserve bank. • Each bank connected to a common header with a separate manifold pressure regulator & and banks alternately supply the pipeline. • Manifold system operates on differential pressure mechanism. • The secondary bank comes into operation automatically when content of the primary bank is exhausted. • Manifold control panel assists in switching automatically between left bank and right bank. • Automatic control panel need no power or electricity requirement for operation. • In case of power failure, control panel has fail-safe mechanism, if required. • Both right and left bank opens in case of power failure and will ensure unobstructed flow to hospital on self-displacement method.
  • 34. PRECAUTIONS WITH MGPS Do not randomly add ventilators on your existing oxygen piping system Consult a biomedical engineer / professional designer Distribute new ventilators across the floor in the different sections of the oxygen piping Construct a high-capacity oxygen piping from the plant from scratch and take it to the ICU unit Train and appoint dedicated manpower across all shifts There should be at least one person at any given point of time who understands the entire oxygen pipeline layout Every ward or every zone should have zone or ward wise drawings of the MGPS with clear indication of pressure settings and valve positions There should be display of the entire oxygen pipeline layout with pressure setting and the valve positions at centrally accessible places in hospitals
  • 35. Oxygen Delivery to Patients
  • 36. OXYGEN CONCENTRATORS- PATIENT DELIVERY CONSUMABLES & ACCESSORIES Patient Delivery Accessories To deliver oxygen from the concentrator to the patient, oxygen outlet adaptors and oxygen delivery tubing are necessary in addition to replaceable nasal prongs and/or catheters. Accessories to divide flow to multiple patients •Flow rate of delivered oxygen must be continuously adjustable by the user •Necessary because oxygen flow needs require adjustment over the course of treatment, particularly important for premature newborns in whom excessive oxygen therapy causes harm •Patients are started at different flow rates depending on their age, clinical condition and the type of breathing device used FLOWMETER STAND
  • 37. Options for dividing flow to multiple patients- Some concentrators have two built-in flowmeters, with two corresponding oxygen outlets, to treat two patients simultaneously. This avoids the need for additional user assembly but is limited to a maximum of two patients that can be treated at the same time. Only some concentrators designated as paediatric have built-in flowmeters capable of titrating oxygen to very low flows (0.1–0.2 LPM). Flowmeter stands consisting of from two to five mounted meters can be used. This has advantage of being more familiar to clinical staff who are used to using flowmeters on cylinders and allows precise titration of flow to each individual patient (including down to 0.1 LPM).
  • 38. • A four-way flow splitter assembly has been used as a method to split flow. • It consists of a four-way flow splitter block, nozzles for 0.5, 1 and 2 LPM and blanking plugs. • Flow splitters are less preferred than flowmeter stands or built-in paediatric flowmeters, since the corresponding blanking plugs are very easily lost or misplaced. • Flow splitters use nozzles that deliver oxygen at a single fixed rate. FLOW SPLITTER, NOZZLES AND BLANKING PLUGS
  • 39. SIMPLE OXYGEN PATIENT DELIVERY INTERFACE EQUIPMENTS •Oxygen cannula – prongs that are placed in the nose for providing oxygen to patient •Oxygen mask – covers lower part of face •Non-rebreather mask (NRBM) – can deliver higher concentrations of oxygen than cannula and regular mask •Exhaled air exits through 1 way valves thus preventing any rebreathing of exhaled air or room air
  • 40. HIGHER FLOW/COMPLEX OXYGEN PATIENT DELIVERY EQUIPMENTS
  • 41. ◦ Oxygen humidifiers are medical devices that can be integrated into oxygen delivery systems to humidify supplemental oxygen. ◦ Humidification is not necessary when oxygen is delivered at relatively low flow rates through nasal prongs or nasal catheters ◦ When oxygen is delivered at higher-than-standard flow rates, or when methods of oxygen delivery bypass the nose, such as when nasopharyngeal catheters are used, humidification is needed – especially when cold oxygen is delivered from a cylinder. HUMIDIFIERS There are various types of humidifiers, and their designs differ in how they apply three main principles : 1. Temperature: As the temperature of gas increases, its ability to hold water vapour increases. 2. Surface area: There is more opportunity for evaporation to occur due to greater surface area of contact between water and gas. 3. Time of contact: There is more opportunity for evaporation to occur when a gas remains in contact with water for long duration.
  • 42. TYPES OF HUMIDIFIERS Bubble humidifier – Non heated (reusable) Bubble humidifier – Non heated (single use) Bubble humidifier – heated Description A reusable bottle that reduces the dryness of oxygen by bubbling the gas through distilled water (or water that has been boiled and cooled) at room temperature. A single-use bottle that reduces the dryness of oxygen by bubbling the gas through distilled water at room temperature. A device consisting of a heat source and a humidification chamber whereby the built-in heater warms the water in the chamber to add moisture to the airstream as it passes over the surface. Merits Simple. No power required. Low cost. Reusable. Simple. No power required. Low cost. Reusable. Adjustable heat for more or less moisture. More efficient at humidifying gas. Drawbacks High risk of contamination (reduced by changing the water frequently) Decontamination required Disposable/single-use. More costly. Risk of “rainout”. High risk of contamination (reduced by changing the water frequently). Needs power source. General Comments Works best at a water temperature of at least 30°C. Works best at a water temperature of at least 30°C. Works best at a water temperature of at least 37°C.

  • 69. Session V: Infection Prevention and Decontaminating Practices for Oxygen Devices
  • 70. Decontamination and Disinfection of Oxygen Supply Devices
  • 71. CLEANING AND DISINFECTION OF RESPIRATORY EQUIPMENT • Equipment used for respiratory therapy is considered semi critical; such items should be cleaned and then receive at least high-level disinfection between patients. • Chemical germicides used for high-level disinfection include • Glutaraldehyde-based formulations (2%) • Stabilized hydrogen peroxide (6%) • Peracetic acid (variable concentrations, but ≤ 1% is sporicidal) • Sodium hypochlorite (5.25%, diluted to 1000 ppm available chlorine – 1:50 dilution)
  • 72. STEPS FOR CLEANING AND DISINFECTION OF PLASTIC PIECES OF RESPIRATORY EQUIPMENT Step-1: Wash the equipment with soap (e.g., liquid dish soap) and clean water. Step-2: Rinse the equipment completely with clean water. Step-3: Disinfect the equipment to inactivate any remaining pathogens: There are several ways to disinfect equipment, Safe methods of disinfection include Heat for heat-resistant equipment that can withstand high temperature (e.g., 80 °C); such equipment can be disinfected using a washer–disinfector. If a washer or pasteurizer is not available, use a high-end or commercial dishwasher with a “sanitize” feature that can reach 70 °C. For plastic equipment that may not tolerate 80 °C and for equipment that may be damaged by boiling, or in the absence of the equipment described above, use chemical disinfection (e.g., soak in 1:100 sodium hypochlorite solution for 30 minutes).
  • 73. DISPOSABLE EQUIPMENT Disposable equipment will be changed in the following manner: • Visibly stained or soiled/ mechanically malfunctioning - Adult ventilator circuits and BiPAP or CPAP circuits, Resuscitation Bags, other equipment's. • Changed daily- Oral care devices (i.e., Yankauer and tubing) on all ventilator patients, Suction canisters, Oxygen masks, nasal cannulas, and oxygen tubing are single patient use. • As needed- o Clear nipple adapters (Christmas trees) on flowmeters are reusable and will be wiped down, after a patient’s hospital stay, by germicidal disposable wipes. o Properly discard Disposable items after use. o Periodically drain and discard any condensate that collects in the tubing of the mechanical ventilator, taking precautions not to allow condensate to drain toward the patient.

  • 74. NON-DISPOSABLE EQUIPMENT Small instruments/equipment will be processed in Central Supply: • Following patient use, items will be washed with an approved detergent and warm water. • Scrubbing will be performed beneath the surface of the water in order to help prevent the aerosolization of pathogens and free of secretions, pus, blood, other debris. • If required soak the equipment for two hours in detergent and warm water. Towel/air dried for 24 hrs. • For sterilization follow a) steam under pressure b) the Sterrad unit (hydrogen peroxide) c) Steris (peracetic acid) depending on the material contents of the equipment and as per Central Service recommendations. • Appropriate personal protective equipment to be worn. Large equipment cleaning/disinfection like mechanical ventilator: • Wipe down the controls and entire outside of the equipment with a compatible disinfectant (e.g. sodium hypochlorite solution of 0.05% or 500 ppm for non-metal surfaces). • Disinfect tubing using sodium hypochlorite solution of 0.1% or 1000 ppm, ensuring that the entire lumen of the tubing is flushed. • As required expiratory side tubing should be disassembled and clean with a detergent, rinse, and then do high-level disinfection or sterilization. • Bacterial and viral filters are recommended on exhalation valves when using for a patient care (ARI). • Only in necessary clean respiratory and pressure lines.

  • 76. Session VI: Ways to Reduce Oxygen Wastage
  • 79. WHY IS THERE SO MUCH MISUSE OF OXYGEN? • Oxygen is safe to use • Easily available in hospital • Availability is considered free of cost • No regulations by higher authorities • No need for permission of any doctor or nursing staff before rotating the knob Oxygen is considered a gas, not a drug ‼ Myths about oxgen ‼
  • 80. BARRIERS TO OPTIMAL OXYGEN USAGE Where Are We Going Wrong??
  • 81. FACTORS LEADING TO MISUSE OF OXYGEN Lack of physician orders on use of oxygen • Need for oxygen therapy • Dose of oxygen (flow of O2, FiO2) • Route of administration (Nasal prongs, face mask, H3FNC, O2 by hood or ventilator) • Period of administration (Continous, intermittent or nocturnal) • Targets of oxygen saturation • Not reviewing oxygen orders regularly
  • 82. FACTORS LEADING TO MISUSE OF OXYGEN Nursing staff • Lack of awareness of side effects of oxygen among healthcare workers and staff • Staff time constraints • Difficulties with changing long established behaviours • Lack of enthusiasm by senior clinical staff • Communication difficulties between doctors and nurses • Lack of full time staff/ Rapid staff turnover
  • 83. FACTORS LEADING TO MISUSE OF OXYGEN • Lack of designated space and place for prescribing oxygen • Notion that all sick patients need oxygen • Higher targets of SpO2 • Patient transferred from other ward with oxygen therapy in situ • Knowledge practice gap • Delay in weaning from oxygen
  • 84. FACTORS LEADING TO MISUSE OF OXYGEN Delivery devices • Incorrect choice of oxygen delivery devices • Inappropriately worn oxygen delivery devices • Non availability of proper oxygen delivery devices at all the places • Non avalability of oxygen blenders to titrate FiO2 • Lack of knowledge about delivery devices
  • 85. FACTORS LEADING TO MISUSE OF OXYGEN Administration • No quality check on oxygen usage • No proper institutional guidelines • Lack of education of healthcare staff about proper usage of oxygen • No oxygen audit
  • 87. FACTORS LEADING TO WASTAGE OF OXYGEN • Inappropraitely increasing oxygen flow o Suctioning o Nebulisation o Cardio pulmonary resuscitation o Transport • Keeping FiO2 to 100% after resuscitation without monitoring SpO2 • Often forgets to close the flowmeter once use is completed
  • 88. CONSEQUENCES OF IRRATIONAL USE OF OXYGEN
  • 89. Side Effects Of Oxygen... Is it so???
  • 90. SIDE EFFECTS OF OXYGEN THERAPY • Dryness of mucosa due to high flows • Elevated PaO2 or hyperoxemia: Increased risk of o Reactive oxygen species o Absorption atelectasis in poorly ventilated areas o Retinopathy of prematurity in newborns o Risk of infection o Mortality o Increased hospital stay
  • 91. • Coronary vasoconstriction - worsening of Myocardial Infarction • Reperfusion injury • Increase in infarct size • Worsening of stroke • False reassurance to the staff • Hypercapnia in patients with type 2 respiratory failure SIDE EFFECTS OF OXYGEN THERAPY
  • 92. • Shortage of oxygen supply for the most needed person • Increased cost of treatment • Deaths due to hypoxemia SIDE EFFECTS OF OXYGEN THERAPY
  • 94. Fire hazard SIDE EFFECTS OF OXYGEN THERAPY
  • 95. Oxygen therapy is a double edged sword...
  • 96. HOW TO PREVENT MISUSE OF OXYGEN ?
  • 97. ASSESSMENT • Assess patient thoroughly • Dyspnea is not the sign of oxygen insufficiency • Consider other causes also o Metabolic acidosis o Anxiety o Pain
  • 98. PRESCRIPTION • Proper prescription of oxygen by doctors • Document target saturations as per patient condition o 94-98% for most acutely sick patients o 88-92% for patients at risk of hypercapnic respiratory failure • Proper recording of instructions over nursing chart
  • 99. ADMINISTRATION OF OXYGEN • Oxygen should be administered by trained nursing staff • Proper selection of oxygen device • Ensure adequate fit to avoid leakage • Adjust flow rate to achieve target saturation range • Use of closed suctioning device to prevent de-recruitment
  • 100. Oxygen source Oxygen delivery systems Interface Oxygen cylinders Wall oxygen Oxygen concentrators Oxygen plants Liquid oxygen Nasal prongs Masks Hood Low flow systems High flow systems Nasal prongs Face mask Partial and non rebreathing masks Hood box Venturi mask HFNC ADMINISTRATION OF OXYGEN
  • 101. SELECTION OF OXYGEN DEVICE Depends on • Age of the patient • Oxygen requirements/therapeutic goals • Patient tolerance to selected interface • Need for humidification
  • 102. MONITORING • Continous monitoring of SpO2 using pulse oximetry • Pulse oximeter should be available wherever oxygen is used • Titrate FiO2 and flow of oxygen carefully based on SpO2 • Record SpO2 on patient chart along with other vital signs • Educate patient about the importance of proper delivery of oxygen • Monitoring of arterial blood gas wherever indicated
  • 103. RECOMMENDATIONS FOR ABG MONITORING • All critically sick patients • Severe hypoxemia (SpO2 less than 94%) • Deteriorating saturation or increasing oxygen demand • Type 2 respiratory failure • Unreliable oximeter signal e.g - due to poor circulation • Dyspnea with risk of metabolic acidosis e.g – Renal faliure, diabetes
  • 104. PROPER GUIDELINES • Formulate & implement local oxygen policy as per the recent guidelines • Introduce standard oxygen prescribing system • Clearly delineating section on drug chart for prescription of oxygen orders • Dedicated oxygen order charts • Standarise bedside documentation of oxygen administration
  • 105. POLICY MAKERS • Regular audits and QI check on proper usage of oxygen • Regular training of doctors, nurse and healthcare professionals • Regular email notification for dissemination of information • Informational posters • Nurse facilitated reminder system • Address the perception of clinicians
  • 106. TREATMENT ALGORITHM FOR EMERGENCY Protocol for use of oxygen in ER should be made
  • 107. WEANING • Formulate oxygen-weaning protocols and guidelines • Follow the proper steps of weaning protocol to improve the patient outcome • Start titration of oxygen once SpO2 has reached the ordered weaning parameters • Weaning frequency, set goals and alarms should be prescribed by a physician • Strike off oxygen from the drug chart when it is not needed • Consider other etiologies if there is difficulty in weaning from oxygen o Low hemoglobin, fluid overload o Lung collapse
