[Treatment] Settings adjustment help

[ispotato]

Hello, I have just had my first night with an APAP and it actually went pretty well for a first night, I think. I did wake up at one point and feel incredibly hot in my mask, which was helped by turning the heat on the heated tube way down. 

During my sleep study, my numbers were 7.5 AHI and 10 RDI, without any central apneas and mostly clustered during REM and later in the night. Last night, it went down to 2.87 AHI, but I started having central apneas, it seems. Though all the CA flags seem to be clustered? I downloaded OSCAR and am looking at the data and am not totally sure what exactly it is telling me.

The current settings on my machine are APAP 6-15, EPR 3, with ramp set to auto. It came just set from 4-20, but I adjusted it a little based on reading here and feeling like 4 felt restricted when I was testing the machine out. It looks like the machine had to bump the pressure later in the night.

Actually, looking at it more closely, I think the CA events might be an error - they're clustered right after I woke up and had to briefly take off my mask to wipe the sweat away. (80 degrees as a default setting for the hose seems kind of wild to me). Maybe the machine mistook me adjusting the mask back on as breathing interruptions.

For now I would just adjust your minimum pressure to 7cmH2O, you need at least 7cm for the EPR to work correctly.  The cluster of apneas after 4:40AM is most likely positional apnea, caused by chin tucking, you may have rolled onto your back or simply got in a position to cause it.  Pressure alone will not fix Positional Apnea, if you can imagine what happens when you bend over a garden hose cutting off the water, but in this case you are cutting off the air.  See lower on the page for a link to Positional Apnea.  The other thing I see is a high tidal volume that I can't explain, perhaps someone else on the forum will know why it is high and if it is actually a problem.  You are actually doing very good for just starting.   

Good luck with your treatment and welcome to the forum.
