Definition

Oxygen therapy is a method of passing extra oxygen to the lungs. It is done to increase the level of oxygen in your blood.

Reasons for Procedure

Oxygen therapy is needed when you cannot get enough oxygen breathing normal air. It is most often needed because of a health problem or injury. Some common reasons that people need oxygen therapy include:

  • Emphysema
  • Chronic Bronchitis
  • Sarcoidosis

Possible Complications

Oxygen therapy is very safe. There is an increased risk of fire around oxygen but basic steps will help avoid this:

  • Keep the oxygen supply away from open flames.
  • Do not smoke. Do not allow anyone to smoke around you.

What to Expect

Prior to Procedure

Oxygen therapy is only given if you have low oxygen levels in your blood. Your doctor will measure your blood oxygen levels. This can be done with a quick scan on your fingers.

A prescription for oxygen will be needed. The prescription will include:

  • How much oxygen is needed
  • How the oxygen will be given
  • When to use it

Description of the Procedure

Oxygen therapy is most often given with a nasal cannula or a face mask. A nasal cannula is a tube that is put just under your nostrils. If you have a stoma, oxygen can also be given through a tube directly to the stoma.

Oxygen may be delivered through one of three systems:

  • Concentrators—electrical device that pull oxygen from the air
  • Compressed gas systems—available in steel or aluminum tanks (including small tanks that can be carried)
  • Liquid systems—include both a large, stationary component and a smaller, portable component to carry oxygen

How Long Will It Take?

The amount of oxygen therapy is based on your condition. It may be needed for a few hours a day or 24 hours a day.

Be sure to follow your doctor's instructions .

Will It Hurt?

Oxygen therapy is painless.

Call Your Doctor

After arriving home, contact your doctor if any of the following occurs:

  • Cough, trouble breathing, or chest pain
  • Gray/blue tint around eyes, lips, and gums
  • Trouble sleeping
  • Loss of appetite
  • You are having trouble delivering the oxygen

In case of an emergency, call for medical help right away.
