Hi I have been using a Resmed S9 for a number of years and just got a new Resmed Airsense10. I find when I am almost asleep it pulses and wakes me up. When my breathing gets low just before I doze off I loose pressure. It seems the machine can't decide whether to pressurize or reduce pressure so I can exhale. My wife uses that same machine and she says hers does it and it's normal but I don't like it. My pressures are set between 7 and 14 same as my old one with no ramp time. I tried with EPR at 1 then turned it off but problem persists. Any suggestions? Increase lower pressure maybe? Thanks
