1. What is Medical Oxygen and what it is used for
Medical Oxygen is a breathed in (inhalation) gas. It is colourless, odourless and tasteless. It is supplied under pressure in a cylinder with a
valve to control the flow of gas. A variety of cylinders sizes are available.
What Medical Oxygen is used for?
Medical Oxygen is used to increase the levels of oxygen in the body’s tissues. It may be used in the following circumstances:

at high concentrations when there is a reduced amount of oxygen being taken into the body through the lungs due to acute or
severe asthma or lung diseases such as pulmonary thrombo-embolism (a blockage of one of the arteries in the lung), pneumonia,
fibrosing alveolitis (inflammation and scarring of the air sacs of the lungs) and pulmonary oedema (a disease affecting the heart).

In low concentrations when there are breathing difficulties due to conditions such as chronic obstructive airways disease
(COAD/COPD) (a collection of lung diseases caused by damage to the lungs)

in the treatment of acute and severe asthma, sleep apnoea (a sleep disorder in which a person has irregular breathing at night
and is excessively sleepy during the day), cluster headaches (attacks of severe, one-sided headaches over several weeks), shock
(a dramatic reduction in blood flow that, if left untreated, can lead to collapse, coma and even death), and in other situations
where localised blood supply is poor

for resuscitation purposes by trained persons, where oxygen supply to the body is reduced due to medical emergency

when the oxygen carrying ability of the blood is reduced such as in carbon monoxide poisoning or severe anaemia (a condition
which occurs when there is a reduced number of red blood cells or haemoglobin concentration)

when gas is trapped in body spaces such as in pneumothorax (air that is trapped next to a lung resulting in collapse of the lung)
or air embolism or other gas disturbances such as decompression sickness (associated with diving)

as a carrier gas or as a diluent for anaesthetic gases or vapours

2. Before you use Medical Oxygen
Interactions with other medicines, medical conditions or diseases
Interactions with other medicines are unlikely when used as directed. However, it is important that you tell your doctor if you are taking, or
have recently taken, any other medicine – even those not prescribed. Unless specially advised by your doctor to do so, do not use Medical
Oxygen if:

you are taking or have recently taken amiodarone (used to treat irregular heartbeat) or bleomycin (given as an injection or drip
to treat some types of cancer)

you have a Chronic Obstructive Pulmonary Disease (COPD) (a collection of lung diseases caused by damage to the lungs)
Take special care with Medical Oxygen
Care is needed in the handling and use of Medical Oxygen – You must follow your Doctor’s instructions.
Fire Risks:

do not smoke or allow those near you to smoke during treatment with Medical Oxygen; smoking during oxygen treatment has
caused serious injuries and can prove fatal

do not allow naked flames in the area where you are using your Medical Oxygen, since even the smallest spark can cause violent
ignition; electrical equipment capable of sparking (including toys which may produce sparks) must not be used where you are
using your Medical Oxygen
Medical Risks:

if oxygen is being used for a premature or newborn infant, they must receive a carefully monitored dose of oxygen. Giving too
much oxygen can damage their sight

if you have a chronic obstructive airway disease you must receive a carefully monitored dose of oxygen

although Medical Oxygen is necessary for patients with lung damage due to poisons such as paraquat (a type of weedkiller), it
may worsen the lung injury; the dose must be monitored carefully
Taking Alcohol and Other Risks:

a slowing down in your breathing caused by drinking alcohol may be made worse by the use of Medical Oxygen

do not breathe Medical Oxygen at pressures higher than atmospheric pressure
Special Circumstances:
Pregnancy
Medical Oxygen can be used if you are pregnant, however, seek medical advice before taking any medicine.
Premature/Newborn Babies
Medical oxygen for premature or newborn babies should only be taken under direction of a qualified medical person.
Breast-feeding
Medical Oxygen can be used if you are breast-feeding, however, seek medical advice before taking any medicine.
Driving and using machines
Non-continuous use of Medical Oxygen at atmospheric pressure will not affect your ability to drive or operate machinery. However, if you
are using oxygen continuously you must be assessed by your doctor.

3. How to use Medical Oxygen
Medical Oxygen will be administered via inhalation and you will be given a facemask, mouthpiece or nasal cannula (prongs) to use, which
are connected to the Medical Oxygen via a suitable medical device. The device must be operated in the manner described by the
manufacturer. The amount of oxygen you will receive is controlled by the type of equipment you are supplied with and the flow rate. You
must use the flow rate prescribed by your doctor and the equipment provided by your supplier.
The flow rate of oxygen used in your treatment will depend on the condition it is being used to treat. Your doctor will tell you how much
oxygen you should use per day and how long your treatment with Medical Oxygen is likely to last.
Other systems used to administer oxygen include face tents, headboxes, cot hoods, a positive pressure mask or a supply to a tracheotomy.
These systems will only be used to give you oxygen under the direct supervision of attendant and suitably trained medical personnel.
Connections for hoses, valves etc. must be kept clean and dry. If necessary clean only with plain water. Do not use solvents. Use clean, lint
free cloths for cleaning and drying off. Do not use oil or grease on any oxygen equipment.
Premature/Newborn Babies
Medical oxygen for premature or newborn babies should only be taken under direction of a qualified medical person.
If you use more Medical Oxygen than you should:
If you may have used more Medical Oxygen than you should, talk to a doctor or pharmacist as soon as possible. However, it is very
unlikely that an overdose will occur.
Using 100% Medical Oxygen continuously for more than a day may produce chest pain and difficulties in breathing. Such a concentration is
likely only to be achieved using specialised (hospital) equipment.
Using Medical Oxygen at pressure higher than atmospheric may lead to convulsions. This is only likely to occur in specialised
circumstances when using decompression units, high altitude mountaineering or diving.
Withdrawal
There are no additional side-effects from withdrawal of oxygen.

4. Possible side effects
Like all medicines Medical Oxygen can have side effects. The toxicity of Medical Oxygen depends upon both the pressure (concentration) of
Medical Oxygen that is breathed in and the amount of time that it is used for. The higher the pressure that Medical Oxygen is breathed in at,
the shorter the time that it can be safely used for.
Side-effects may include:

giving too much oxygen in newborn and premature infants can damage their sight and may be associated with other damage
(these conditions have more than one cause and can occur even in the absence of oxygen therapy)

lung damage from prolonged giving too much oxygen - symptoms include shortness of breath, cough and chest discomfort

central nervous system toxicity if Medical Oxygen is breathed in at pressures of twice atmospheric pressure or more as in
hyperbaric oxygen therapy. This would normally only occur in specialist hospital treatment. Symptoms could include nausea,
mood changes, vertigo, twitching, convulsions and loss of consciousness
If you notice any side effects not mentioned in this leaflet please inform your doctor or pharmacist.

5. How to store Medical Oxygen
