School Me - EPR (EPAP) & Flow Limitations
#21
RE: School Me - EPR (EPAP) & Flow Limitations
The mechanism for PS working on flow limits is not to reduce Expiratory Pressure Intolerance in my personal experience.
I'm quite comfortable up to 16cmH20 (no EPR) exhaling, but I'll still experience flow limits (0.3+), that's how the pressure went up to 16+ on my Dreamstation.
With EPR set at 3 on my Resmed my flow limits are well under control (0.16-) while the overall pressure sits in the 9-10cmH2O region.
It seems to me that EPR3 treats the flow limits before they ever turn into RERAs or hypopneas, and I think it's got something to do with shots of extra pressure on inhale to help open the airway on a breath by breath basis. constant pressure doesn't seem to work as well.

My guess is that my particular condition involves a gradual narrowing of the airway, as opposed to others who experience a faster complete collapse of the airway.
My wife has often said she's never seen me gasping for air. My sleep study showed no apneas, just hypopneas.
