Oxygen Concentrator

What Is an Oxygen Concentrator?

An oxygen concentrator is a medical device that gives you extra oxygen. Air is made up of about 20% oxygen. An oxygen concentrator uses the air in the atmosphere, filters it, and gives you air that is 90%-95% oxygen. Your doctor may prescribe one for you if you have a health condition that causes your oxygen level to drop too low, such as:

1. Asthma
2. Lung cancer
3. COPD (chronic obstructive pulmonary disease)
4. The flu
5. COVID-19
6. Sleep apnea
7. Heart failure
8. Cystic fibrosis
9. Bronchitis
   

More than 1.5 million Americans use an oxygen concentrator for supplemental oxygen therapy. Oxygen concentrators can be rented or bought, depending on whether you are using it for short-term therapy or long-term treatment. You need to get your doctor’s OK before you buy or use an oxygen concentrator. Using one without their guidance or a prescription can be dangerous and cause lung damage. If the doctor thinks a concentrator might be right for you, they’ll let you know how much oxygen to take, how long to use the device, and how to use it properly so it doesn't interfere with your daily activities like bathing, working, and sleeping.
