When EPR = 1, the pressure drop is still leaving you with enough exhalation pressure to prevent most of the events; but when EPR = 3 the exhalation pressure is now low enough to allow more events to sneak by.From Sleepyhead
Out of curiosity: What are your median and 95% pressure levels? If you're getting AHI < 1 with EPR = 1 at these settings, then it's possible that you were a bit over titrated in the lab.
AHI = 0.47 (Hyp=0.16, O = 0.31)
- Pressure = 9.8
- EPAP = 8.8
- Leaks = 19.2
CPAP set at 13 was very un-comfortable, back pressure on Ears almost deaf, Headache, even dizziness. Thats when I decided to convert from CPAP to APAP on my own in hopes of making it more bearable. First I reduced the pressure from 13 to 9 than increased to 9.8. I can handle this pressure. Now, working on minimum pressure and EPR levels.
EPR = 3 is comfortable but high, AHI. EPR =1 is uncomfortable but acceptable AHI.
Next, I plan to increase minimum pressure to about 7 and set EPR =2. I hope that will give me the right answer.
