Are "events per hour" on the MyAir App the same as AHI ?

I am in high single digits.
If no changes after next appointment I will start adjusting things myself

thanks.

I emailed, tweeted and called ResMed - they won't talk to me about firmware versions.
I thought i would give it a try anyway

Just called them and asked for the full report. They said "it's just a bunch of charts you won't understand" .. but they claim they are mailing it all to me in tomorrows mails. I'll believe it when I see it !

They really are resistant to giving this out. They finally mailed me a crappy photocopy - see attached I hope it's readable. 

By the way, the last couple of nights I am AHI 4.9 - still in APAP 4-20 mode. 
Always AHOI in single digits now and sleeping rock solid 8 hours of actual sleep with mask time.
I don't even wake up at all, no more tossing and turning at all.
Also c-collar fixed by previous neckaches and numb morning arm!

Next appointment is 8/15.  I am hoping he will tighten up the 4-20 setting.

Thanks for looking at these charts

In your earlier post the results summary indicated that at a CPAP pressure of 9.0, nearly all of your apnea events were eliminated.  I was skeptical and essentially said "fat chance" and asked for the more detailed pages.

[Image: attachment.php?aid=7320]

The details "you won't understand" clearly show abundant apnea is present at a pressure of 9.0 in this graph.  The graph lacks a detailed pressure or time on the axes, but we can interpolate each horizontal line as 4-cm pressure increments and the vertical lines has hours. So we see you started at about 5-cm pressure and moved to about 9.0 cm just before the second hour. There were about 3 OA events before you entered a quiet period of sleep that included the only period of non-supine sleeping that lasted until until hour 3:25 when an arousal occurred (wake) until a therapy break where pressure dropped back to zero.  The period from 2:45 to 3:25 at pressure 9.0 was very good and importantly you were mostly on your side.

You appear to have been mostly awake until hour 5 when you fell into N1 and N2 sleep. At about 5:30 pressure was increased to 11-12, and this corresponds to a large cluster of apnea (back sleeping).   At hour 6.5 pressure was increased to approximately 13 cm. During this entire period you had abundant OA and some HA with mixed and central apnea emerging at the higher pressure.

This is your typical sleep pattern from what I have seen in past posts.  You tend to have both quiet and active apnea periods with more central events emerging at higher pressure.  It was tempting for the doctor and technician to interpret the quiet period at pressure 9.0 as a successful titration, but it ignores that returning to pressure 9.0 during the apnea clusters failed to break it (06:00 and 7 :15).  It also is illogical that higher pressure resulted in a progression to severe OA and higher pressure resulted in mixed and central apnea.  

What this chart tells us is you really benefit from staying off your back! It also tells us you don't suffer significant oxygen desaturation with the increased clusters of events, however there are brief periods where SpO2 approaches 92 that correspond to the apnea.  High pressure is not your friend, and neither is sleeping on your back.

that image insert of PAGE 2 "DISTURBANCES OF SLEEP"
is NOT mine - you must of inserted it in error?????
or did you want me to read it for some reason.
Not sure what it is, or why it's there. It's not mine.

*THANK YOU*

That's a very interesting analysis

I have been sleeping on my back, because on my side - I get mask leaks.

I will work on sleeping on my side without leaks. I think I can achieve that after a few nights.

So maybe APAP is better than CPAP for me?

I see Dr again in 12 days and look forward to seeing if he makes any pressure changes.

Also seeing the ENT Doctor in about 3 weeks. Looking forward to his opinions too

Thanks

I misread it for sure

Sorry

You said sleeping on my side produced best results.
I did exactly that with the c-collar on and ....  

[drum roll please]...

AHI  1.9  !!!!!!!!!!!!
