Adjusting Expiratory Pressure Relief (EPR) in ResMed S8 Elite 2

In order to adjust the Expiratory Pressure Relief of the ResMed S8 Elite II, your machine must be set up by your clinician to allow you to make the adjustments.

Your ResMed S8 Elite 2 has four adjustment levels for your expiratory pressure relief (EPR).

  1. OFF (no EPR)
  2. 1 (lowest EPR)
  3. 2
  4. 3 (highest EPR)

To adjust your EPR, enter the programming mode on your ResMed S8 Elite 2 CPAP machine. To change the EPR level, select the left slash to the left of the up and down arrows. Press the up arrow or down arrow until you see the setting that you require.

The EPR LEVEL screen appears only if your clinician has enabled access to the EPR settings.

    Mine ramps up to full nm pressure but now it seems it is on blast all of the time.

      The air pressure will blow full bast if the machine senses a leak. Please make sure you have the correct mask size and that there are no rips or holes in your CPAP equipment. If you still need assistance please reach out to our customer service representatives at 1-(866)414-9700.

    highest EPR means? less pressure when you exhales?
    I put it on 1, but didn’t know what it meant… it was off…And they were wanting me to buy a bipap machine so it would allow me to exhale without so much resistance.

      The higher the EPR, the lower the pressure drop on exhalation. For example, if you have a setting of 10 with an EPR of 3, the pressure drop will be to 7.
