Stationary Concentrators

The stationary oxygen concentrator is designed to provide an unlimited supply of supplemental oxygen to patients whose blood oxygen saturation is 88% or less.

Our atmosphere is comprised mostly of 21% oxygen and 79% nitrogen. The oxygen concentrator removes the nitrogen component, creating an oxygen-enriched environment, which is between 90% and 96% oxygen.

To maintain optimal performance of your concentrator, the following guidelines are recommended:

  • Place the concentrator in a well-ventilated area.
  • Plug the concentrator into a well-grounded electrical outlet. Never use an extension cord.
  • Do not smoke or come within 5 feet of heat source. (Example: if you want to cook, remove the nasal cannula and leave it in another nearby room.)
  • Do not use petroleum-based products such as petroleum jelly, for nasal dryness or irritation.
  • Do not use an oxygen mask with a concentrator.
  • Make sure there is no more than 50 feet of oxygen tubing on the concentrator.
  • Make sure your oxygen tubing is not kinked or obstructed.
  • In the winter months, do not use wool blankets or anything that may cause static electricity around the oxygen concentrator.


  • At least weekly, remove the cabinet filters and wash with warm soapy water, rinse thoroughly and dry.
  • Weekly, wipe down the concentrator with a clean damp cloth.
  • Never open the concentrator cabinet. Any internal maintenance will be done by your provider.
  • Studies have shown that humidifiers are not necessary for liter flows of 4 liters or less per minute. Humidifiers can be connected to the concentrator to add extra humidity at higher liter flows.
