5. Storing Medical Liquid Oxygen.
The name of your medicine is Medical Liquid Oxygen. Medical Liquid Oxygen is supplied as a pure gas containing only oxygen. It does not contain any other ingredients.
1. what is medical liquid oxygen and what it is used for.
Medical Liquid Oxygen is an inhalation gas (a gas that is breathed in). It is colourless, odourless and tasteless. It is supplied as a liquid gas (at very low temperatures) in a cryogenic vessel.
Oxygen is essential for life. Oxygen breathed in with air goes into your lungs where it is taken into your blood. The blood carries the oxygen to all your body tissues. The tissues take the oxygen from the blood so that they can work properly.
If, for any reason, you are not getting enough oxygen into your blood from your lungs you may be given Medical Liquid Oxygen to breathe to increase the level of oxygen in your body tissues. You will be able to breathe more easily.
Medical Liquid Oxygen is used when you are not getting enough oxygen into your body through the lungs due to lung disease or damage or when you have breathing difficulties.
It is used in the treatment of cluster headaches and other conditions where localised blood supply is poor.
It is used with anaesthetics during surgery and for artificial ventilation in intensive care after surgery or following an accident.
It is used as a propellant for inhaling other medicines in nebuliser treatment.
It may be used in pressure chambers to reduce the risk of damage as a result of gas bubbles in the blood vessels or if there is gas trapped in body spaces. When the oxygen carrying ability of the blood is reduced such as in the case of severe carbon monoxide poisoning. It may also be used as part of the treatment of gas gangrene (damage to soft tissue caused by bacterial infection)
2. before you use medical liquid oxygen
Do not smoke or allow those near you to smoke during treatment with Medical Liquid Oxygen.
Oxygen helps things burn. Oxygen can cling to fabrics. Smoking during oxygen treatment has proved fatal (due to fire and burns) to more than one patient.
Do not allow naked flames near you when you are using your Medical Liquid Oxygen.
Unless specially advised to by your doctor to do so, do not use Medical Liquid Oxygen:
- If you are taking or have recently taken amiodarone
- If you are taking or have recently taken bleomycin (a drug for cancer)
- If you have chronic severe airways disease.
Take special care with Medical Liquid Oxygen
If you suffer from a chronic lung disease you should only receive a carefully monitored dose of Medical Liquid Oxygen – Carefully follow your doctor’s instructions.
If Medical Liquid Oxygen is being used for a premature infant, the infant should only receive a carefully monitored dose of oxygen. – Carefully follow the doctor’s instructions
Although Medical Liquid Oxygen may be necessary for the treatment of patients with lung damage due to poisons such as paraquat, it may worsen the lung injury.
A slowing down in your breathing caused by drinking alcohol may be made worse by the use of Medical Liquid Oxygen

3. how to use medical liquid oxygen
Always follow the instructions given to you by your doctor. Do not stop treatment or change your treatment without consulting your doctor first.
You will normally use Medical Liquid Oxygen by breathing the gas in through nasal prongs or through a mask. The nasal prongs or mask are connected to the Medical Liquid Oxygen via specialised equipment that you will be supplied with.
Only use the equipment supplied to you for use with your Medical Liquid Oxygen
Always follow the instructions for use for the equipment. You should only use the flow rate that your doctor has instructed you to use.
All equipment used with the Medical Liquid Oxygen should be kept clean and dry. Do not use oil or grease on any equipment that is used with Medical Liquid Oxygen.
Take care with the use and handling of Medical Liquid Oxygen as contact with Liquid Medical Oxygen can cause cold burns.
Do not attempt to repair any equipment supplied to you for use with Medical Liquid Oxygen. Contact Air Liquide to arrange the repair of any faulty containers.
Other systems that may be used to administer Medical Liquid Oxygen will be only used to give you oxygen under the direct supervision of attendant and suitably trained medical personnel.
The concentration of oxygen used in your treatment will depend on the condition it is being used to treat.
Your doctor will tell you how long your treatment with Medical Liquid Oxygen will last.
If you forgot to use Medical Liquid Oxygen
Take your Medical Liquid Oxygen as soon as you remember, do not take a double dose to make up for the forgotten treatment.
If you use more Medical Liquid Oxygen than you should:
If you may have used more Medical Liquid Oxygen than you should, talk to a doctor or pharmacist as soon as possible.
It is very unlikely that an overdose will occur.
Using 100% oxygen continuously for more than a day may produce chest pain, a dry cough and may also cause breathlessness. Such a concentration is only likely to be achieved using specialised hospital equipment.
4. possible side effects
Like all medicines Medical Liquid Oxygen can have side effects.
If Medical Liquid Oxygen is used at high concentration (greater than 40%) for a prolonged period of time (more than 2 days) then lung damage can occur. Symptoms of lung damage include shortness of breath and chest discomfort.
In newborn and premature infants treatment with oxygen at concentrations over 40% can damage eye sight and may be associated with damage to other organs. These conditions have more than one cause and can occur even in the absence of oxygen therapy:
If you receive Medical Liquid Oxygen in a pressure chamber (hyperbaric oxygen treatment), you can suffer from ruptured ear drums, sinus pain, passing muscle pain. This treatment can also have effects on the central nervous system, which could lead to nausea, dizziness, agitation, confusion, muscle twitching, unconsciousness and epileptic seizures. The higher the pressure within the chamber the earlier these symptoms will be seen.
If you notice any side effects not mentioned in this leaflet please inform your doctor or your pharmacist.
