understanding data on my elite 2

[Slinky]

24 L/M = 0.4 L/s

Awwwrrrrgghh!!! Math is NOT my forte!
60 (seconds in a minute) x .80 per second = 48.00 or 48 L/m
60 x .78 = 46.8 L/M

And then we have to add the 10 L/M so those two 95the percentile leak rates would be 58 L/M and 56.8 L/M.

Is that right, BillBolton???

ok thanks
i am new to this
question
my leak rate is going to be off because i am not using a resmed mask
i know that now .i cant change that i have a good seal .78 l/s
will my other reading be somewhat acurate
ahi 22 ah 13 hi 9
my pressure reads no data for the last 3 nights ...not sure why ....leak rate too high ???
also if i can get a detailed reading with my smart card on a computer resdata 3,7 will i be able to see a more detailed readout
times of my ah and ai perhaps leak rate
i thankyou dan

You do NOT have a good seal yet w/your mask. Your reported Leak rate is .78 L/s.

If you have your
1] Mask Selection correctly set at Standard for your Fisher & Paykel HC 407 nasal cushion mask
2] and your pressure is set at 9 cms
3] the allowed vent rate for the HC 407 at 9 cms is 34 L/M
4] the Resmed subtracts 24 L/M from the leak rate BEFORE reporting the 95th percentile on the LCD screen when Mask Selection is set to Standard
5] so a reported Leak rate of more than 10 L/M is excessive and will somewhat distort your AHI data
6] your Resmed is reporting the 95th percentile Leak rate in L/s rather than in L/M
7] so you need to "translate" that 10 L/M into L/s to know what L/s is excessive Leak for you

Also, the Elite II CPAP gives no pressure data for most of us. That bit only exists in the menu because they use the same software in one of their APAP machines, which does give pressure data. Just ignore the no pressure data.
