Leakage data

My philips machine has consistently give me 100% on mask fit with zero leakage, but sleepyhead just this morning told me I had major leakage events last night, and when I looked backed i see ( on sleepy head) lots of leakage. Who is right ????

The machine is correct.

copied for the thousandth time from what I have said to others.

Disregard that warning from SH. Your leaks are NOT excessive.
Instead the statistic reporting the % of time in large leak is based on a ResMed calculation number and that number won't work for your Respironics machine.
Open SH and go to Preferences and then the CPAP tab. SH Defaults to a red line leak threshold of 24 L/min which is a ResMed leak number...won't work with your machine. Your red line threshold number is more like 75...so change the 24 to 75 or just turn off that statistic by removing the check mark.

Large leaks (if you have any) will show up as flags on the Events graph and are a product of the machine.
Those are correct....the SH statistic is just a product of some calculations and isn't from the machine and in your situation with your type of machine...it's wrong.
Ignore it and base your leak evaluation on the presence of large leak flags on the Events graph...the LL on the events graph...that's large leak.

Oh, more than a thousand time, that 'issue' in sleepyhead has caused problems.

That's one of the things I tried to get fixed, in my 'heinous' abuse of the programmer..
