  If the red alarm indicator is illuminated and the setting number isn't flashing during inhalation on your Precision Medical Oxygen Equipment, it means no breath has been detected for 2 minutes. First, check that the cannula isn't kinked. Next, make sure the cannula is properly connected to the oxygen outlet and correctly positioned in your nose. If the alarm continues, switch to an alternate oxygen source and contact your equipment provider.
