1. WHAT IS LIQUID MEDICAL OXYGEN AND WHAT
IS IT USED FOR
Liquid Medical Oxygen is supplied and stored as a liquid at
very low temperatures, in vessels and storage tanks. It is
converted to Medical Oxygen, a gas at normal temperatures,
for you to breathe when required. In hospitals, the converted
Medical Oxygen is supplied via a medical gas pipeline
system.
Medical Oxygen is used:
• during anaesthesia and for recovery following surgery
• to treat or prevent oxygen deficiency in the body in
many different situations such as:
- surgery or major trauma such as a road traffic
accident
- heart attacks

This leaflet gives you information about:

2. THINGS TO CONSIDER BEFORE USE
Medical Oxygen is only prescribed to you by a
healthcare professional.
Ensure that your healthcare professional is aware of any
medical conditions that you may have.
Take special care when using Medical Oxygen if:
• your baby requires extra oxygen and is premature.
Only give the amount of Medical Oxygen advised
by your healthcare professional
• you are suffering from chronic lung disease, such
as bronchitis or emphysema. The amount of Medical
Oxygen used must be carefully controlled to the
flow rate you have been advised to use by your
healthcare professional
• you have accidentally taken Paraquat (a type of
weed killer), advise your healthcare professional
before using Medical Oxygen, as there is a possibility
of toxic effects to the lungs

• do not apply any direct heat to the affected area
• place the affected area(s) in lukewarm water
• use sterile, dry dressings to protect the damaged skin.
Your clothing could become saturated with oxygen if
either liquid or excessive gas comes in contact with it. If
your clothing becomes saturated you should walk
around in a well-ventilated area for 15 minutes, keeping
well away from naked flames and sources of ignition.
Taking other medicines
If you have been taking or prescribed Bleomycin (to
treat cancer),Amiodarone (to treat an irregular
heartbeat) or Nitrofurantoin and similar antibiotics (to
treat infection), advise your healthcare professional
before using Medical Oxygen, as there is a possibility of
toxic effects to the lungs.
Tell your healthcare professional if you are taking or
have recently taken any other medicines, including
medicines obtained without a prescription.

Pregnancy and breast feeding
As Liquid Medical Oxygen is stored as a very cold liquid under
pressure, rapid opening of the outlet valve will either cause
very cold gas or liquid to be discharged. If this gas or liquid
comes in contact with the skin it will cause cold burns. Parts
of the vessel can also become very cold, when in use. This
will be evident by ice forming on the cold sections and care
should be taken not to touch these areas.
If you have received a cold burn intense pain may be
experienced when the skin starts to thaw. To treat cold
burns:
• loosen any clothing restricting blood flow and get medical
help immediately

Medical Oxygen will not affect you or your baby if used
during pregnancy or whilst breast feeding.

Driving and using machines
You may drive and use machines after using Medical
Oxygen providing that your healthcare professional
considers that you are both fit and capable.

equipment when you receive your first supply.

When using your Liquid Medical Oxygen at home directly
from your vessel, you must:
• ensure the vessel is stood upright on a flat surface and
supported so that it will not fall over. Liquid Medical
Oxygen vessels should only be used in the vertical
position with the valve uppermost, to prevent liquid from
being spilt

DO NOT SMOKE or have a naked flame near your Liquid
Medical Oxygen vessel. The oxygen will make
a flame burn much more violently.

NEVER use oil based moisturising creams with your
equipment.
If you use more Liquid Medical Oxygen than you
should

• ensure that all equipment is kept free from oil and grease

questions on the correct use of Medical Oxygen, please
ask your healthcare professional.

4. POSSIBLE SIDE EFFECTS

5. HOW TO STORE LIQUID MEDICAL OXYGEN VESSELS

Like all medicines, Medical Oxygen may cause side
effects, although not everybody will get them.

Expiry date

The side effects that may occur whilst using Liquid Medical
Oxygen are:
• soreness of the chest associated with coughing and
breathing difficulties after breathing pure oxygen for
a prolonged period (6-12 hours). This is made worse
by smoking and exposure to cold air
• dizziness, fits and loss of consciousness after
2-3 hours of exposure, which can occur if you are
treated with high pressure (hyperbaric) oxygen in
pressurised chambers
• eye damage (retrolental fibroplasia) which can result
in blindness, which may occur with new born babies
if they are exposed to oxygen concentrations of more
than 40%.
Reporting of side effects
If you experience any of these side effects, or if you notice
any side effects not listed in this leaflet, contact your
healthcare professional immediately.
You can also report side effects directly to the Medicines and
Healthcare Products Regulatory Agency (MHRA) via the
Yellow Card Scheme www.mhra.gov.uk/yellowcard and to
BOC Healthcare. By reporting side effects you can help
provide more information on the safety of this medicine.
