I have been a member of this forum for a while and have benefited greatly from the information here, however this is my first post so please bear with me.
Recently a problem has developed with my therapy that I need help solving. I have been using the ResMed S9 Auto and the AirFit P10 very successfully for almost a year. Last night I fell asleep as usual and woke up after a couple of hours with great difficulty breathing. There was plenty of air flow coming into the pillows from the machine, however it seemed like I was working very hard to exhale, almost hyperventilating! I checked the mesh vents on the mask and it seemed like there was very little air coming out. Eventually I had to remove the mask and shut off the machine, which was very upsetting as I've had 100% compliance since I began the therapy.
My mask is clean, including the vents. and appears in good condition. Tonight I will use a new set of pillows to see if that helps. The EPR on my machine is set to 3 and up until now that has worked fine.
My question, is this a mask problem, or could it be a problem with the S9 (about 1 1/2 yrs old)?? I really don't know where to start in diagnosing this issue. Any help would be greatly appreciated.
Thank you so much!
