Apnea Duration

What was the duration of your longest apnea?

My longest apnea was 46 seconds, and the hypopnea was 68 seconds. Overall, ageraging 22 events per hour.

I think of all those minutes, and seconds, and its day/wks/mos. of a lifetime, huh?

My lowest O2 sat. was 79% (low). Had severe hypoxemia. Guess when my feet hit the floor, it's a good day, with all this news.

huh?

Gailzee,

It makes me sick when I do the math!

My longest apnea was 26 seconds, my longest hypopnea was 64 seconds... but my lowest blood saturation was 59% (!!!!)
My RDI (is that average resporatory incidents?) was 110 (!!!!) which one of my doctors had said was the largest she'd ever seen.
My average number of arousals per hour was 41.7.

The diagnosis was "very severe".

This was on my first sleep study. I don't know what the figures were on my second study where they were calibrating the CPAP, but I'll ask for them the next time I see my sleep specialist (which is tomorrow).

Oddly enough, my pressure setting is 12. I wonder if that's because I'm tending to have hypopneas more than apneas?

And, yes, I am 100% compliant. I felt so much better even the night they were doing the second sleep study (which was full of interruptions and all those uncomfortable sensors) that I'd be utterly insane not to wear that mask every single night.

I don't feel like a "moring person" yet, but it's early days yet (coming up on 6 months) and my OSA is so severe, I wonder if it's actually impossible for the CPAP to make up for that completely. But maybe that's just my pessimism speaking.

RubyKat,

I am trying to zone in on the critical factors that the specialists get most alarmed by; you've give me fodder for another question in the forum. Thanks.

You're very welcome.

Hello all,just thought I would give my stats from the report/cpap titration trial.


Slept 82 min. Rem time 0 minutes,etc.
Rem sleep and stage 3 and stage 4 were not identified.
Total of 72 obstructive events 71 hypopnea events. 0 central events,0 mixed events. 118 of these events were associated with a oxygen desaturation. 132 arousals 118 were associated with a respiratory event and desaturation. 16 were spontaneous arousals. 0 PLM episodes
apnea/hypopnea index: 104.6,severely abnormal.

cpap titration was done; 11 centimeters of water pressure got the apnea-hypopnea index into the normal range at 0.7.

Impression:Severe OSA

And I thought I did not have sleep apnea.Just being tired all of the time from age,etc. As I look back I can see all of the signs that I missed.
My sister sent me to the Dr. for the test,she saw me doze off one day,and gasp for breath.
Thank goodness for her, I would still be falling asleep talking to people,etc.

I am adjusting well to the cpap and mask.
My next goal is to lose a bunch of weight.
I wish everyone luck with their problems.

Hello,

I am new here -- my sleep study was on 12/3/04 and I finally got my machine on 1/10/05. I am adjusting to the mask (NasalAire II) and machine (ResMed S7 Lightweight with the heated humidifier) all right. I have been modifying the headgear so that the NAII doesn't move around, but mostly doing ok. I am using the machine all night, and tolerating it fairly well.

I got a summary copy of my report this week, and my longest apnea was 111 seconds, with an average of 78 OSA's per hour. I was titrated at 14 cm of H2O. No centrals, no hypopneas. I was less than 90% desat 50% of the time, with some falling below 60%.

I am not falling asleep at work now, and have a little more energy, but still tired at the end of the day. I don't think that I am snoring with the machine, but don't really know (I live by myself). I am not waking up as much as pre-CPAP - that is also a welcome change!

These numbers do not seem to be close to what I have been reading about here while "lurking" for the last few weeks, but from the reading, are alarming. I am concerned about the accuracy of the sleep study -- it seems that I would have been in worse shape than I was with those numbers. I was tired, high blood pressure, lots of extra weight, and I struggle with Meniere's Disease in one ear.

I have had problems with bloating and my ears feeling pressurized. I would like to move to an autopap machine, and spoke with customer service at cpap.com today -- Ted was a BIG help! Thanks Ted!

I am hoping that an autopap will decrease the negative symptoms and still treat the OSA symptoms, and I would like to track what is happening. I am leaning towards the PB 420E with heated humidifier & software. I also travel some, and think that the light weight and small footprint of the 420E would be nice!

I don't know if I gave enough detail for an informed opinion, but would like to know if you experts out there would like to give me your opinion about the use of an autopap and software to track with my situation.

I apologize in advance if I got any of the "lingo" wrong or gave too much or not enough information! I have never used an online forum before -- I had to call my son for help!

Thanks,

Jane

Jane, you (and your son ) did great. I enjoyed reading your post and wish you everything good in your continued treatment!

Sorry folks - that was me that got this back in action. But it looks like a good poll that needed resurrecting

Just doing some research on the lies of buteyko and wanted to know what the longest apnea was.

The video that got my attention was this one -

My longest apnea was 50 seconds

But no more.

cheers

During my sleep study my longest apnea event was 62 seconds with an AHI of 119. So far on treatment and my AHI averaging 2.9 over the past 14 days and my longest apnea event was 49 seconds during treatment the first couple of weeks, most are between 12 and 25 seconds now.

No problem Mars. I did sort of wonder there for a minute what happened...
Anyway, you have me beat in the apnea duration race but not by much. I was told 45 second in my sleep study.

LOL I misread your post and as I watched the link I was thinking 'this is absolute rubbish!'. I was all ready to come back and tell you so when I noticed "on the lies" in your post.

Am I interpreting this correctly? You were titrated in less than 1.5 hours?

I don't think a proper titration can be done in so little time.

During my sleep study, I had an AHI of 108, with longest apnoea lasting 92 seconds Can't remember the desats but they were quite bad!
Really incredible that I never had any symptoms except bad oxygenation of the blood that showed in my blood tests!
