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.

What are the Uses and Applications for medical oxygen?

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.

How does Medical oxygen help you?

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.

Other uses for Medical Oxygen

Medical oxygen is colourless, odourless, and tasteless. It is classified as a respiratory assistance gas, which means it is essential for human respiration. Oxygen is administered for many reasons in a medical setting. Hospitals, surgery centres, dental offices, and veterinary facilities can use medical oxygen for:

  • First-aid resuscitation for medical emergencies
  • Medical procedures that require anaesthesia
  • Life support for patients who cannot breathe on their own
  • Oxygen therapy for treating low levels of oxygen in the bloodstream
  • Home Oxygen Therapy
  • Sedation or Anesthesia/Analgesia
  • Acute & Chronic respiratory cases

Medical oxygen is also used in high altitudes, for underwater breathing, and in hyperbaric chambers.

While the air we breathe is a mixture of carbon monoxide, hydrogen, nitrogen, and oxygen, medical oxygen is 100% pure. Impurities can make people sick, so the highest standards are enforced for medical oxygen. No other types of gases or contaminants are permitted in the cylinder.

How to Order Medical Oxygen with Mega Medical

We offer medical oxygen refills to dentists, veterinarians, hospitals and aged care facilities with free delivery to all areas of Sydney. If you are looking to order medical gas for your practice or hospital, you can order easily online or over the phone. We accept orders via our online form, or give us a call and we can organise delivery.

Who can administer medical oxygen?

Medical oxygen requires a prescription from a medical practitioner authorised to prescribe medications. Home medical oxygen therapy is prescribed only for patients with signs or symptoms of chronic hypoxaemia.

Most medical oxygen is administered in hospitals, surgery centres, dental practices, and veterinary offices. Face masks, nasal cannulas, and hyperbaric chambers deliver medical oxygen therapy to patients. Nurses, doctors, and other approved medical providers receive training on how to administer appropriate levels of oxygen to patients.
