Any body may let me know more about EPR in Resmed S9?
I know it's somehow related to making exhale easier, but what's the logic of numbers 1-2-.. and "patient" mode?
I feel to have better sleep on patient mode, but how it works?
And why my upper pressure in the morning always reads quite near to the Max Setting in APAP mode? may it mean i'm currently on a low setting?
WELCOME! to the forum.!
Yes EPR is for when you breathe out and there are three different levels you can select, or you can turn it off if you decide that you don't like it, its a comfort feature.
Hang in there for more answers to your question and best of luck.
EPR is indeed a pressure relief for exhale. The 1,2,3 values are measured in cmH2O, the same way that the pressure is measured. For ResMed machines, when the machine detects an exhale, it will reduce the pressure by the EPR value from its current setting (down to a minimum of 4) until the next inhale is detected. [ For Philips Respironics machines, it will reduce the pressure by the *Flex setting until the end of the exhale is detected. ]
According to your profile, your pressure range is extremely narrow (from 14.2 to 15 cmH2O). It's not surprising that the limits will be reached. Personally, my pressure needs do range all the way from 11 cmH2O to around 19 cmH2O, depending on my sleep position, the phase of the moon, etc.
