I am trying to train to breath through my nose with the pillows and its working except a feeling of difficulty breathing out at times. Would this undermine the therapeutic effects and make it difficult for the machine to reach optimal pressures? Thanks for your advice.
You can set EPR to 3, but with your pressure setting of 4-20, EPR won't kick in until the APAP reaches a pressure 7. Then you would get exhale relief of 3cm, and you would then be breathing against a pressure of 4. The APAP can't go lower than 4cm no matter what EPR setting you use.
EPR does not make it difficult to reach optimal pressure, has nothing to do with it, but with a starting pressure of 4, it could take the APAP longer to reach optimal pressure, and possibly miss some apneas.
