Pressure seems to drop after about 1 minute
I have a ResMed S9 Elite. When the machine 1st starts, the pressure seems fine (plenty of pressure during inhale and exhale). After about 1 minute it drops to the point where there is little to no pressure when inhaling or exhaling. The display shows the correct setting when running. I have ramp and EPR off. This happens on both my old machine and the new one. It also happens across all pressure settings that I have tried (12-20 cmH2O). Thanks for any help.
