Why has the DeVilbiss Medical Equipment airflow stopped and reports mask leak?
- DDennis GreenSep 13, 2025
The airflow may have stopped unexpectedly, or the device may report a mask leak due to: * The Auto-STOP feature detecting a large airflow because of a loosely fitting mask. To resolve this, make sure you have a good mask fit by adjusting the mask and headgear. * Mouth breathing during use. Contact your equipment provider for a chin strap or a different mask to prevent mouth breathing. * The optional humidifier chamber not being fully engaged or is missing. Slide the humidifier chamber fully into the cradle, and verify the release latch clicks into place. * The air supply port plug missing or not fully inserted. Ensure the air supply port plug is fully inserted into the device.
