RE: [Moving from Dreamstation CPAP to Resmed VPAP S/T] Need some help
What we can't know is the duration of the UA events or how they arise. They seemed to go away on ST mode, although we don't have much data on that. Congrats on your improvements, and hope to see further progress when you start ST.

RE: [Moving from Dreamstation CPAP to Resmed VPAP S/T] Need some help
Hi all,
Just a quick one: I am now running 12/7 (PS5) with "High" Trigger and most of the hypopneas and UA follow the pattern as per the attachment.
I am here facing a dilemna: shall I try 13/8 (PS5) with "high" trigger or keep 12/7 and set "very high" trigger in order for the BiPAP to be more sensitive with my inhale attempt?
RE: [Moving from Dreamstation CPAP to Resmed VPAP S/T] Need some help
the pressure wont change anything if you are not attempting to breath I see no attempt to inhale during the UA listed so there is nothing to force the machine to change to IPAP pressure. That is where the Timed mode comes in.

Then I am confused why the flow rate looks like I am trying to breath 3 times during the UA? But not enough to trigger the IPAP.

I interpret that chart differently. The three wave deflections during the UA are all expiratory (below zero line). If there is inspiratory effort, (and there may be some), it is weak, and they seem to happen at the same interval or rate as your preceding breath rate. I think this is why ST works for you to deliver a breath when you hypoventilate. The same pattern is evident for the hypopnea, but for a shorter duration. BTW, I like the mask pressure chart here, and really miss seeing that in the Philips charts. We can see how the end of the UA and H events results in a more sustained IPAP.

Thanks Sleeprider, I guess that it answers my question then: I should try to set my trigger to "very high" in order for the sensor to be very sensitive when it comes to detect any inhale attempt, in order to try to be most of the time in "Spontaneous" mode.
Then, T must be used the least of the time. Also, right now I am in "high" mode.

Does your machine have an option for Easy-Breathe? You are getting square-wave pressure, and Easy-Breathe would shape that to look more like cresting waves.

Hi Sleeprider, Jas,
Indeed the AirCurve 10 does not have "Easy-Breath" feature, however there is a "rise" time that can be set, in order to smoothen the transition from EPAP to IPAP: 150ms, 200ms, 300ms, etc. For now, I have set it to 150ms.
Attached the results of yesterday night, as well as an Excel table that I have created. I can see a trend emerging, where the AHI is increasing of +1 every time I increase the EPAP of +1. So I guess, I don't need the kind of pressure I am currently trying out.
From tonight onwards, I will move from "high" to "very high" trigger, and start lowering the EPAP of 1 night after night, until I reach EPAP=5. All this is S mode only.
If the trend of the AHI moving down is also confirmed, I will select the best EPAP between 5 - 8, based on the lowest AHI.
Then I will active ST mode from that moment onwards.
