What to do if airflow stops unexpectedly during use with DeVilbiss Healthcare SleepCube DV57?

If the airflow stops unexpectedly, it could be due to several reasons. The Auto-OFF feature might have detected a large airflow due to a loosely fitting mask, so ensure you have a good mask fit and adjust it along with the headgear. If you start mouth-breathing during use, consider using a chin strap or a different mask. Also, make sure the optional humidifier chamber is fully engaged and the air supply port plug is fully inserted into the back of the CPAP.
