Is my S9 Autoset Malfunctioning?
I have been struggling for a few nights with poor mask fit, so I'm wondering if this is related.

For the past three nights, my total usage number has been less than it should have been. Today, I downloaded my data and found that my machine recorded 11 mask events last night, even though I did not once get out of bed or turn the machine off. There should be one event for 8 hours and 1 minute, and instead it shows 11 and only 4 hours and 59 minutes of being on.

Could it be treating all the times I adjusted my mask as event, and if so, any thoughts on why are there three hours of lost time?

Hi Taxman Derek
Are you using SmartStart feature? if not, unplug, wait few minutes and plug, rebooting helps reset the machine
Does gaps also shows on detailed graph? I've not read that the S9 stop when detect high leak rates (some machines do and have leak alarm when leak reach at ceratin point) just ResMed saying their machine can compensate for leak at 24 L/min and high leak rates compromise therapy and affect accuracy of the data

As for leaks, its not surprising at your pressure 19, I would have a problem using Quattro with pressure above 10.
Have you tried nasal mask? for most people mouth breathing is a habit than anything else

You can benefit setting the machine on autoset mode, in this mode, the machine adjust pressure breath by breath as needed and might not touch 19 most part of the night or even not at all. Lower pressure means better mask fit and better mask fit means better therapy

Based on the information guide, the S9 display a message "High leak, please check system setup and all connections" when excessive leak detected (page 4) http://www.resmed.com/au/assets/document...ac_eng.pdf

You are probably having leaks around your mask at that time.

Look at your data for big leaks.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
