according to the resmed autoset manual, the max flow it can handle at 20cmh2o is 136lpm. at 12cmh2o, it says it's good for 164lpm.
seems that there should be plenty of breathing room over that 24lpm.
The 24 lpm is over and above the vent rate which if memory serves is 20-50 lpm. The real problem however is not the ability to supply the air but its ability, with increased air flow to sense the things that it responds to and to sense the apneic events.
BINGO~! My point and concern. I cannot find any good data to learn at what point will *my* machine not be able to accurately read and understand events due to leaks?
I slept very well last night with my 'Wisp'. But the leak rate bounced between 20-30l/p, and showed an AHI of 7 (good for me) - but the graphs didn't show any jaggies - more like curves - so am thinking data was degraded.
Again, minor or random leaks - no biggie - but sustained higher leaks?? That makes me wonder if I should cave to the FFM and just suffer?
