Getting New Aircurve 10 Bilevel today

Profile updated. Thanks.

Question:   What can I do to lower my "CA" numbers?

Attached is my sleep data from last night.

1. Zero OA & Hypopnea.  All " CA" .  All happened during the period when I tried to fall asleep, but couldn't. I recall waking up at 3 am and couldn't fall asleep for a long time.

2.  Is it because I can't breath that cause me not to be able to fall asleep or it is because I can't fall asleep that cause me not to breath properly?  For a healthy person lying in bed, it would seem that breathing is easier & better while in awake state.

Should I reduce the PS from 4 to 3.6 to bring the EPAP & IPAP closer together?

Should I increase the trigger from "High" to "Very High"   ?

Slam, we have found that changing the trigger sensitivity to high or very-high can significantly reduce CA events. Start with high and go higher if needed. It simply reduces the amount of flow needed to trigger IPAP and as a result can stimulate a breath when you otherwise might miss one.

Sleeprider,

Trigger is already on "high".    I will try "Very High".

Also, the reason I suggested lowering the PS from "4" to "3.6" to bring the EPAP & IPAP closer together is because previously on my old Airsense 10 APAP machine, EPR was set at "1" and the EPAP & IPAP was much closer together.  EPR "3" gave me unsynchonous  breaths .  Since the new machine is Bilevel, I imagine the pressure support is much better than the EPR from a single motor machine.

You still have a single motor, that provides the bilevel pressure, and as far as I know it is identical to the Autoset pneumatic block. We learned with the 10 series that all Resmed units are essentially the same machine with different firmware on the main board. That said, there are significant differences in the bilevel controls. Reducing pressure support is a logical response to CA events and the point is to find where you're most comfortable. Nothing really stands out on the chart as a problem, other than you have a couple CA clusters, probably related to sleep transition. Give the Very High trigger sensitivity a try and understand that most of these issues usually diminish as you adapt to the improved ventilation of this therapy.
