[Pressure] Needing help with pressure setting on APAP.
#1
Needing help with pressure setting on APAP.
Hello all! I'm new to APAP, OSCAR, and apnea board. Thank you for taking the time to check out my post and assist. I am not sure what pressure setting to have my APAP on as the past week I am having events more than 5 nightly and have been sleeping poorly. I had most success with just over 5 events at pressure setting 8 to 14. I changed my setting last night to 9 to 20 and recorded over 8 events. I could really use some guidance with selecting the correct pressure setting as I did not have a titteration test due to being prescribed an APAP. Any and all help is appreciated as I feel truly lost. Thank you!!

Should I turn my EPR to 0 or 1? After additional research on the forum I believe it may be causing CA.

RE: Needing help with pressure setting on APAP.
possibly, though I do not think you'll be as comfortable.

If this were my chart, I would select an EPAP level targeting above the bottom of the shark teeth, and then add whatever EPR with that to get my start IPAP pressure. I would select an EPAP of about 7.8, and choose to back off the EPR to 2. That would mean I would start with 9.8 IPAP and EPR = 2. I would pick an upper limit (20? 15? 12?) it only matters if you are awakened by the higher pressure.

If a really liked the EPR=3, I would have to increase my starting pressure to 10.8 to ensure I am not exhaling at lower pressure than 7.8.

Yours,

RE: Needing help with pressure setting on APAP.
Last night I adjusted my APAP settings for pressure as well as EPR. I slept very poorly and I think my data reflected that. I have no idea how to get my CA events down and I am totally confused as to why I'm having them since I was only diagnosed with OSA.

I am feeling totally defeated here.

Thought apap adjusted automatically. Mine just adjusts as I sleep up or and down in pressure.

quesadilladaddy,

Did Clear Airway events show up on your sleep study? If CA's didn't show up on your test, then they should lessen in time.  

If you have a copy of the study, even without having the titration test, post it here.  

Higher pressures are not a friend of CA's. For now, I would go back to the 8.8cm and turn EPR off.

I don't believe CAs were present on my sleep stufy from what I can tell. It was an at home study with a WATCHPAT. I'm going to attempt to link my sleep stufy results in another reply.

I can't post links yet on here due to being a new user. But i will try to upload some of the files.

It was an at home test using WATCHPAT. I don't think CAs showed up during it to my knowledge.

RE: Needing help with pressure setting on APAP.
You had 3.1 central AHI in Rem sleep and 0.7 in non-Rem. So you have some centrals on your diagnostic. That Means these are most likely not TECA and of unknown origin or idiopathic at this time. This means the action recommended by myself and others will most likely not reduce your CAI below what it is on your EPR1 chart (Reddit).

Still turn off EPR and see if we get lucky.

Also be aware that central apneas show up up with what we call a consistently inconsistent frequency. In other words CAI often jumps all over the place unless you are treating it with a machine that is designed to treat centrals such as an ASV. Having a CAI of over 5 is one of the criteria for getting an ASV

Look in settings/Comfort to turn EPR off.
