EPR reduces pressure when you're not inhaling, subtle, but sometimes important distinction. Thanks for the graph. It does show the EPR behaviour more clearly than the simplistic explanation provided by ResMed. However, when you're neither inhaling nor exhaling (a pause in breathing), wouldn't it ma...

According to ResMed:
How does EPR work?
When you breathe out (exhale), the flow generator device (if EPR is integrated) detects the beginning of exhalation and reduces motor speed to drop treatment pressure.

6 nights in a row I can't fall asleep. My unit is set to auto-ramp from 4 to 15 over 40 minutes once I fall asleep. The problem is even at 4.0 pressure the resistance I get is enough "bother" that I can't fall asleep. Did you turn on the EPR feature? It automatically reduces the pressure when you e...
