Liquid Medical Oxygen is supplied and stored as a
liquid at very low temperatures, in cylinders 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 to you via a medical gas
pipeline system.
Medical Oxygen is used:
• during anaesthesia and for recovery following
• 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
• severe blood loss
• carbon monoxide poisoning
• severe lung and heart conditions
• very high fevers
• for resuscitation of adults, children and babies.

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.
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
cylinder can also become very cold, when in use.
This will be evident by ice forming on the cold
sections and care should betaken 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.

• 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 come in contact
with it. If your clothing becomes saturated you
should walk around in a well-ventilated area for 5
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.

used during pregnancy or whilst breast feeding.

Instructions for use
Liquid Medical Oxygen is only given to you after

room temperature. In a hospital or clinic Medical
Oxygen will be given to you by a healthcare
professional. They will ensure that your Medical
Oxygen supply is suitable for your use and that the
equipment has been set up correctly so that you
receive the right amount of oxygen.
To breathe your oxygen you will either be given a
face mask or a nasal cannula. The prongs on the
cannula are inserted into your nostrils and the
tubing is placed over your ears and adjusted under
your neck for comfort. The face mask or nasal
cannula is connected to your oxygen system with
the tubing provided.
If you are using a Liquid Medical Oxygen cylinder
at home you will be given full training on the use
of your cylinder and equipment when you receive
your first supply.
When using your Liquid Medical Oxygen cylinder at
home, you must:
• ensure the cylinder is stood upright on a flat
surface and supported so that it will not fall
over. Liquid Medical Oxygen cylinders should
only be used in the vertical position with the
valve uppermost, to prevent the liquid from
being spilt.
• check the contents gauge on the vessel before
you start to make sure there is enough gas
available for your use.
