Why is the S9 leak always 6 liters/minute ? - Doctor - 10-24-2015
Six liters per minute leak seems like quite a bit. I read that up to 24 liters/minute is okay. My mask isn't leaking, so where are these six liters per minute going ?

The S9 display 95th percentile unintentional leak (from mouth, mask, etc.), means leaks was at or below 6 L/m (not all long) for 95% of the night. If stuck at 6, might need rebooting

Yes, 6 is on the screen but SleepyHead shows zero. Have rebooted the machine several times in the past year. I was told not to worry about the value until it exceeds 24.
Does anyone here have a leak of zero on their S9 screen ?

I've only ever seen that once, just after I switched to a Simplus mask. As Zonk said the leak given on the machine is the 95 percentile. It could be caused by a transitory event like your mask being nudged slightly out of place if you move in your sleep. Unless leaks are causing you problems (eg blowing into your eyes or causing face-farts) then I wouldn't worry about it.

SleepyHead shows ... Min, Med, 95%, Max
Which one showing zero?
I'm not sure of the definition of Min, mine always zero
I'm not fussed about leak, as long as don't disturb my sleep or goes near my eyes

The one year of CPAP Stats on SleepyHead shows Average Leak Rate = 0.00, 90% Leak Rate 0.00, and % time above Leak Rate Threshold = 0.00 .
But the ResMed S9 screen never shows a leak rate of 0.

I cannot imagine how could be zero for everything all this time, but then I don't have much of imagination

Have you tried ResScan, but doesn't like Mac

Good point, Zonk.
Will try ResScan.

Interesting!!! I just looked at my leak rate statistics in Sleepyhead. What caught my interest was the fact that my average leak rate is 1.49 for the last 6 months and 1.43 for the last year. My 90% leak rate is 0 for the last 6 months and 0 for the last year. I do not think that this is mathematically impossible but it is mathematically improbable I think.
Frankly, I seldom look at the statistics in Sleepyhead.
Best Regards,

Sounds like an issue with the Sleepyhead and the S9. Mine seems to read okay.
6-months
ALR: 7
90% LR: 15.4
