EPAP Pressure

Post by Jtg073 » Wed Aug 09, 2023 10:23 am

What are some signs that EPAP pressure needs to be higher?

I don’t understand how EPAP helps to prevent obstructions to your airway. Isn’t that what IPAP does? And EPAP is just the pressure resistance as you’re exhaling? Is EPAP only about comfort as you’re exhaling? Is there a benefit in raising the EPAP pressure? Does it actually help keep the airway open?

EPR lowers the pressure when you exhale.
When the pressure is lower, your airway is more apt to collapse. And keep you from inhaling, even before IPAP is applied.
Keep in mind that both inhale pressure and exhale pressure are there to keep your airway from collapsing. The don't "blow open" obstructions. They're there to prevent them.

Didn’t get a notification for your reply for some reason. Thanks, that makes sense. Is EPR the same as pressure support?

Both refer to the difference between inhale pressure and exhale pressure.
The technological implementation and the way the machines create that difference is not identical.
But both aim at making exhaling easier.

No, EPAP is what holds your airway open so that you can take another breath, if EPAP is too low, then you can't start to take a breath, because your airway is blocked, and IPAP never comes in to play.

EPAP is the pressure *between inhalations*.

Are you confusing EPAP (Expiratory Positive Airway Pressure) and EPR (Expiratory Pressure Relief)?

EPR is the *opposite* of pressure support, EPR DROPS pressure, PS RAISES pressure.
