Determine acceptable mask leakage

[Gary1of2]

I could use a little help trying to figure out mask leakage. How to detrmine what the leakage amount is acceptable.

Sleepyhead is pretty good at showing when you have excessive leakage.


With SleepyHead look at your Leak Rate graph where it is shaded (large leak/ LL), flat tops on this graph suggest mouth breathing. In SleepyHead right click on the left header of the Leak Rate graph and click on Dotted Lines then select "Leak Rate Upper Threshold" to get a line across the graph for ResMed. Manually set the value for Philips Respironics. Severity depends on how much over this threshold and for how long it is in the Large Leak territory.
