  If the yellow Low Oxygen light is on, or the yellow Low Oxygen light is on and the intermittent audible signal is sounding on your DeVilbiss Health Care Products unit, make sure the flow meter is properly set to the prescribed number. Check the air filter and wash it if it's dirty. Also, verify that nothing is blocking the exhaust area. If these steps don't solve the problem, contact your DeVilbiss provider.

  If your DeVilbiss Health Care Products unit operates, the Power light is on, but the Red Service Required light is illuminated, and an audible alert may be sounding, consider the following: Check the air filter and wash it if it is dirty. Check the exhaust area to ensure nothing is restricting it. Detach the cannula or face mask; if proper flow is restored, clean or replace them. Disconnect the oxygen tubing at the oxygen outlet; if flow returns, inspect the tubing for obstructions or kinks and replace if needed. Detach the humidifier; if proper flow is obtained, clean or replace it. Finally, ensure the flow meter is set to the prescribed rate. If problems persist, contact your DeVilbiss provider.
