Oxygen Therapy: Using Oxygen at Home

Oxygen therapy helps you get more oxygen into your lungs and bloodstream. You may use it if you have a disease that makes it hard to breathe, such as COPD, pulmonary fibrosis (scarring of the lungs), or heart failure. Oxygen therapy can make it easier for you to breathe and can reduce your heart's workload.

Some people need extra oxygen all the time. Others need it from time to time throughout the day or overnight. A doctor will prescribe how much oxygen you need and how often to use it.

To breathe the oxygen, most people use a nasal cannula, people who need a lot of oxygen may need to use a mask that fits over the nose and mouth.

How to use oxygen therapy
If you need oxygen at home, it is important to learn how to use and take care of your equipment.

Do not drink alcohol or take drugs that relax you while using oxygen.
Alcohol, sleeping pills, or sedatives and other drugs can make you breathe too slowly.

Take care of your nasal cannula.
Wash your cannula with a liquid soap and warm water daily. Replace it every 2 to 4 weeks.
If you have a cold, change the nasal prongs when your cold symptoms are done.
Use oxygen safely.
Oxygen is a fire hazard. It will make a flame burn hotter and faster.

Never smoke or vape or let anyone else smoke or vape while you are using oxygen.
Keep oxygen at least 2 m (6 ft) away from flames, sparks, or heat sources.
Do not use flammable products while you are using oxygen.

Let your doctor know if you:
Feel short of breath.
Feel restless or confused.
Feel very tired.
Feel like you are not getting enough oxygen.
Travelling while on oxygen therapy
Travelling while you are on oxygen therapy usually is possible if you plan ahead.
