Please help interpret Sleepyhead results

[lastmango]

Hi all,

Thank you in advance for your help and this board! I have been on CPAP therapy for a few years and things have gone pretty well, low AHI, etc. but the past few months I have been feeling more tired, etc. I need to refresh my understanding of the terms, results, and Sleepyhead software use, but in the meantime I'm kind of desperate for some quick help and some direction. Attached are my results overview, and my results from last night. Not sure what changed on May 19th, or why I seem to have some results missing from prior to that time? Thank you!

The reason the results are strange prior to May 19th there is no detailed data for these dates and tha effects the figures calculated by sleepyhead.


Your cpap figures look pretty good

I wonder why there is no data? I have had the same machine, etc. for a couple of years, and I think the last mask change was last year some time.

Most mornings my Auto Set says that my mask is leaking alot, I get the sad face...do my Sleeepyhead results show an unacceptable leak rate?

I also noticed that my AHI has increased, I realize it's still pretty good, but something has changed and I don't feel as good.

That would be applicable for a S9, but not for an air10 machine.

As you know, I forget to put my SD card back in the machine occasionally. So I can weigh in on this topic. On my Airsense 10 Autoset, the AHI numbers that SH reports when no detailed data exists are always off, and they are always low from the numbers the machine shows. A couple of weeks ago the machine showed AHI 2.2 when I woke up. SH import was 0 8 AHI. This got me paying attention to it And I've had "opportunities" to compare over the past week.

I used my machine for a good 5 weeks before starting to use SH. I downloaded ResScan so I could do some comparisons of AHI over this time. All of the SH numbers are off on the low side. Sometimes alarmingly so.

This is ONLY when SH imports just summary data. When detailed data exists, the numbers always match.

Any feedback on the leak rate?

It's *terrible*.

Should be 24lpm or less.

I *believe* that Jas was referring to the way the S9 deletes high rate data after 7 days and detailed data after 30... so to get all the good data, you have to import at least once a week.

The Air10 doesn't delete data off the card until (maybe) the card starts to fill up, so it doesn't need to be imported weekly.

I see. And thanks for those tidbits of info. They all go into the hopper.

I think I shouldn't have quoted you. I'm pointing out that prior to may 19th, there's only summary data. Based on my experience, all the AHI values in the posted overview chart prior to May 19th aren't worth hooey. OP states that AHI has gone up. If that conclusion was drawn from the posted overview chart, I don't believe it's true. I see the same in my overview charts.

The grey usage lines in sleepyhead mean summary data only, maybe the user did not have an SD card in the machine upto that point so no detailed data recorded!!!

Just stating facts.

Leak???

Is this a typical night...the best night...the worst night?

Are those leaks waking you up or are you sleeping right through them?

You could be right. maybe he didn't have a SD card before that.

I’ve definitely had the card in the machine all along, this is the first I’ve removed it in a couple of years. Yes, my comments on the increased AHI are due to the overview information only.

I do sometimes wake up from a leak, or my wife nudging me because a leak is waking her up, but I would say 90% of the time I sleep through the night. I think my pressures are fairly high, and I’m using nasal pillows with a chin strap so it makes sense I’m leaking just not sure why it’s apparently leaking more and I don’t feel as rested?

[lastmango]

Pale rider, curious about your comment on my terrible leak rate. And I noticed you are using pillows as well. Do your pillows seal very well, have you had issues, etc?

I had been using 7 or 8 different full face masks per my Dr’s recommendation due to my high pressure and they all leaked and frequently woke me up. The pillows worked and were comfortable right away but I needed the chin strap because I’m a mouth breather.

Here's my latest chart I've got handy while using the P10. My pressure sometimes gets up into the low 20s, though not that night.


Maybe your strap is too loose?

Chin straps don't prevent mouth breathing... try clenching your jaw, you can still breath quite well through your teeth, because they're not air tight. taping, or a boil n bite mouth guard will cut down on mouth breathing.
