Wonderful, thanks a lot!
RE: Expiratory Relief and Preliminary Report Analysis - DrAHI - 02-27-2019
Hello everybody,
This is my latest APAP report, after a few days spent figuring out how to make things work. I started to use the machine about 5 days ago.
Equipment: As in my profile, with the addition of a cervical collar.
O2 Saturation during the day is within normal parameters (Measured with D50H)
Mode Auto with Soft Response.
I am still unhappy with the results, as you can see, even though I had a drastic decrease of AHI events. As a reminder, I start from an AHI of 61.
I suspect some of the events flagged by the software are false positive?
Also, why does it say that I was in bed for 25 minutes and awake for hours?
Any feedback and comments on how to improve would be greatly appreciated.

It says that you were in bed from just after midnight (00:25)AM 0r 12:30 until 0925 or 9:25AM so you were there for 9 hours.
That said how well did you sleep? Did you dream a lot?
You still have a lot of flow limitation and significant apnea.
Try a pressure range of 17 to 20 with EPR 3
And for sure get a hold of your doctor.

You are going to end up with a bilevel machine (Aircurve 10 Vauto). Fully justified based on your pressure and lack of efficacy with CPAP.

Thank you for taking the time to read the data, Fred.
To answer your questions and to give you a little more context, as there are factors that may influence the therapy:
I sleep in very uncomfortable conditions in a very tiny space (long story, but hey, it's Hong Kong!)
I started to use a cervical collar two days ago
The latest data do not represent the best results I got. After two days of use, I managed to get a 15 AHI (no use of a collar, but still figuring out how it happened... For your reference I attached the report for that night).
I can barely feel the air and the humidity (level 4 now) in my mask (F20), and the mask is astoundingly silent. Is that normal? Does the mask/tube/air pump work properly? Is there a way for me to test that?
The doctor initially prescribed a nasal type of mask, but I am a mouth breather at night. I would tend to sleep on my side, but since I started the therapy I sleep on my back. Would another type of mask be more beneficial?
Immediate benefits noticed: Sleep throughout the night without having to go to the bathroom every two or three hours (never happened in years).
Do not wake up anymore with headache or a heavy head. Do not fall asleep suddenly during the day when sitting, often in embarrassing places...
Problem noticed: the bottom side of my L size mask (the silicon part on the chin area) sometimes slips up and uncovers my mouth. I have no idea why, but I guess it's a matter of mask fitting and night movements.
Thank you again.

Hi all,
In the attached screenshot there is my best performance so far.
I am still getting used to interpreting the data, but I think the graph shows once more that a Bi-Level machine with more pressure is most probably the right device for me.
Thoughts?
Thx
RE: Expiratory Relief and Preliminary Report Analysis - Gideon - 03-05-2019
You are correct. A bilevel is in your future
If the pressure of the VAuto (4-25) is enough pressure then it will be the best machine.
If you need higher pressure than perhaps the PR ST which goes up to 25 EPAP and 30 IPAP

Thank you for the reply.
I am not familiar with the PR ST, but I hear it is not produced anymore?

I think bonjour's main point was that some of the more specialised machines will go up to 30 or 40cm, if that is needed. I haven't read all the posts, I take it you have tired postural changes, flat pillow and a foam cervical collar to see if you are tucking your chin and closing your airway during sleep.
