[Diagnosis] Chart diagnosis

[Rodgui]

Hi to all. I Am new here, so bare with me on my problems. I have been on Cpap since 2022, and in the last couple of months my AHI'S have gone up. Used to be just over 5, but now are all over the place. I will attempt to insert last nights results and hope someone can put me on the right track regarding my settings etc. Thank you.

Welcome to Apnea Board!

First thing I notice is the Positional Apnea or better known as "chin tucking".  This is evident by the apneas clumped together.  You are sleeping in a position that is cutting off your air, usually from sleeping on your back on more than one pillow or a too tall of a pillow that allows your head to tilt forward.  Note that chin ticking can also occur while sleeping on your side.  

I've attached a link for you to read.  Compare the "clumping" of apneas to the graphs in the link.  You will either have to change the position in which you sleep or start using a soft cervical collar.

Normally, pressure changes won't help with this issue, but I'm going to recommend some changes anyway while you work on your Positional Apnea.

The minimum pressure of 5 is too low.  Your pressure zooms up to 10 due to Flow Limitation.  I suggest you set the minimum pressure to 10 and the maximum to 15.
Set your EPR TO 3 (full time). (This will help you breathe out against the pressure easier, and hopefully tackle FL and leaks.

Work on that Positional Apnea!

Thanks for your recommendations. I will change my settings and also my pillow which is a bit higher and harder than usual. I sleep on my left side but do move around a lot during the night and generally end up on my back near morning. I find I have been having quite a few mask leaks which is not helping, so I have been concentrating on getting a good seal before sleep. Was getting "red faces" on my machine nearly every night, but this has now settled down. I have attached last nights data and once again, thanks for your insight.

Welcome to the forum Rodgui, OpalRose is right on the money with the pressure change suggestions and setting EPR to 3. Your last chart has quite it massive bit of hyponeas and flow limits so these changes should really help out your therapy and your comfort

Thanks for your reply. I have run with OpalRose's suggestions and readjusted my machine pressures. Also trying a softer pillow. Will see what tonight's readings bring.
Kind Regards.
