Low AHI, high flow limits

[theswerve]

Hi all,

I've been able to largely eliminate my positional apnea clusters with a cervical collar which has lowered my AHI quite a bit but I continue to wake up multiple times throughout the night with flow limits typically over 0.1. My EPR is already at 3 (with CPAP fixed pressure at 9). I've attached last night's oscar as an example. Any guidance would be greatly appreciated.

You do not have enough pressure as can be seen in the OA and H events. You can either try increasing the fixed pressure a bit each night until something happens or titrate using APAP mode with a min-max range. Your choice.

If you want to titrate start with this:

Mode APAP
Min pressure 10
Max pressure 15
EPR 3 full-time
No ramp

Then, if it does not bump up against the max of 15 after a few nights, you can take the 95% and use that as a fixed pressure. If it does bump up to it then you need to increase it a bit each night until it stabilises.
