Some call it EPR, others call it FLEX, and still others call it Reslex. Regardless of the name they are all exhalation relief settings. These settings are designed to give the CPAP user an easier time exhaling. It does this by reducing the pressure by a certain amount every time it senses you exhaling. This simple adjustment can make a huge difference in your CPAP Therapy experience. Below, we will go over this setting in the major models in detail.
ResMed CPAP Exhalation Relief – EPR
EPR stands for Exhalation Pressure Relief. It can be adjusted from 0-3 in increments of 1. At an EPR setting of 0 you have no exhalation relief at all. At a setting of 3 you get 3 cm of pressure relief when you exhale. So, for instance. If you have your ResMed CPAP set at a Therapy Pressure of 10cm with an EPR setting of 2, then you will inhale at a setting of 10cm and exhale at a setting of 8cm.
How to adjust your EPR setting on your ResMed CPAP (AirSense 11):
From your Home Screen press the blue “My Options” icon.
Adjust your “Pressure Relief” on or off. That setting should be right under the “ramp” setting.
The Flex Setting on Respironics CPAPs and Bipaps has been around for a very long time. It is available in all of their models, and may be referred to as AFLEX or BiFLEX in different models. It is adjusted from 0-3 as well.
