Definition

• An oxygen concentrator is a device used for patients that delivers a high concentration of oxygen by separating oxygen from ambient air. Oxygen concentrators are often used in home health care and anesthesia.
  
  

How It Works

• An oxygen concentrator sucks in ambient air, which consists of 21 percent oxygen and 78 percent nitrogen, and filter out the nitrogen, leaving pure oxygen to be compressed and pumped into a tank for patients to use. Both standard and mobile oxygen concentrators run off of regular power sources as well as on batteries.
  
  

Generator Power

• In case of a power outage, if batteries are not an option, you can run an oxygen concentrator off a small generator. A generator that uses between 400 and 1,500 watts will give the concentrator enough power.
