What's Unacceptable Leak

[Snorzz]

Been on the machine for 15 nights now and tolerating it well; feeling much more rested.  My 95 Percentile leak runs from around 4 to 12.  Is that acceptable?  I quit using the chin strap after the first night or two; I seem to be able to keep the mouth closed without it --- or am I kidding myself?  Maybe it opens and I don't know it?  If so, though, wouldn't the leaks tell me?

On the ResMed machines any over 24ml is a large leak. Your well below that so even if you have some leak it's not affecting your treatment.

Your leaks are well under the threshold where your therapy would be impacted.  If you want to see whether and to what extent the leaks you do have may be mouth related download Sleepyhead (see the link in Walla's signature).  Once done, check the leak rate graph.  Generally speaking, if you see leak spikes with flat tops (as opposed to curved or spiked) that usually means mouth breathing.
