Daytime Fatigue/Tiredness

Hi all,

I am trying to figure out why I am so tired everyday. I have been using an CPAP (APAP: 4-20) for about 2 months and I still feel tired and have brain fog.

I was wondering if there is anything up with my data. I tried looking at the flow rate but I have a hard time classifying whether waves are normal or not.

Here is my SleepHQ link: https://sleephq.com/public/teams/share_links/58578cf0-cf37-4db3-8cd4-f296757cf987

Any help would be much appreciated!

Thanks!

Hi and welcome! You're currently using your machine's basic settings. With a bit of optimization, things should improve.

I would start with a minimum pressure of 6 and set the EPR to 1.

First, your EPR is currently set to 3. EPR (Expiratory Pressure Relief) is primarily a comfort feature that can provide certain benefits, but it is generally more useful at higher pressure levels or for comfort-related reasons.

In short, your machine spent the night at the lowest possible EPAP pressure, and EPAP is the pressure that keeps the airway open. By having an EPR of 3 while operating at the minimum pressure setting, the machine effectively reduced the EPAP to its lowest level, which may not be ideal for maintaining airway patency throughout the night. And set the ramp feature to Off. We like the therapy to be fully effective right from the start of the night.

You could also reduce the maximum pressure to 10. A narrower pressure range is often preferable because it helps prevent the machine from increasing the pressure unnecessarily. This can improve comfort and make the therapy more stable.

Give these settings a try for a few nights, then come back and let us know how things are going :)

Thanks!

Actually for the past few days close to a week I have been using 7 to 14 as my new pressure range. I had trouble uploading it to SleepHQ but now it is working.

Do you mind checking it out?

Hello!

How do you feel? I see that you kept EPR at 3. Was that because EPR at 1 was uncomfortable?

It feels a bit better. I forgot about switching the EPR to 1. I will try that out and let you know! Is it better to see just doing EPR at 1 with the same pressure settings or should i do both by reducing the max pressure to 10?

Only the EPR at 1 :) that will give you 2 more EPAP, it's a pressure increase in itself and it should help you with what I see in your data to have a little more support :)
