What is Medical Oxygen?

Medical oxygen is a high grade oxidising gas made of 100% oxygen. It is odourless, colourless and tasteless and commonly stored as a compressed gas until use by medical professionals.

While it is known for saving lives, it is important to follow the gas storage rules to ensure it does not become dangerous. We offer an easy to download Gas storage checklist here.



Uses and Applications

Medical Oxygen (gaseous) is used whenever you are not getting enough oxygen into your blood. This situation is called hypoxia. You can suffer from hypoxia if you have breathing difficulties due to respiratory disease, chest wounds or rib fractures. Hypoxia is also seen if you are in shock, bleeding badly, have a heart attack, have other heart problems, or have carbon monoxide poisoning.

Since a high level of oxygen saturation is required for cell metabolism, medical oxygen is used in these situations to ensure patients are getting the correct amount of oxygen to survive.

It works by helping you to breathe more easily via either a face mask, nasal cannula and in some situations hyperbaric chambers. Oxygen is also used as a diluent for other gases used during an anaesthetic.

Complementary Products

Medical oxygen is a one of the most widely used gases in the medical profession due to its broad range of uses. When setting up a practice for medical oxygen use and maintaining its systems a number of key products are required. The Series O Medical Oxygen Regulator by Comweld is the most popular product for low flow oxygen administration and use. Complementary to the regulator is the oxygen flowmeter which can come in a few different models depending on the flow rate and application. Additionally, it is important to set up routine inspections of your Gas Bottles along with regular medical oxygen deliveries to make sure you don’t run out in an emergency.
