Seeking Clarification on EPR

[RER9372]

I use a ResMed Air Sense 10 APAP and I currently have my EPR set to 3 and I had some questions on that - if my EPR is set to 3, will it not kick in until the APAP hits a pressure of 7? If the pressure hits 6, will an EPR of 2 kick in? Or how exactly does this work? Thanks!

ResMed's EPR (Expiratory Pressure Relief) setting is a comfort feature that reduces the pressure delivered during the exhalation phase of the breathing cycle.

ResMed CPAP machines have a minimum pressure setting of 4 cm H2O (centimeters of water pressure), thus, any EPR will not be usable below this minimum. 

Example: The EPR feature will be active throughout your entire therapy session, regardless of whether the pressure is at the minimum or maximum level. So, if your minimum pressure is 6 cm H2O and your EPR is set to 3, you will experience a pressure of 4 cm H2O during exhalation.

An EPR of 3 would require a pressure of 7 to be fully effective. 
An EPR of 2 would require a pressure of 6 to be fully effective.
An EPR of 1 would require a minimum of 5 to be fully effective.

Hope this helps.

This helps immensely. Thank you!
