Reading REM Sleep from Sleepyhead

[AVMO]

I've searched and is apparent Im not asking it right...I'm trying to find where on Sleepyhead data it shows REM sleep....also what is acceptable leak % TIA for your help

My leak % seems high to me but I don't hear or feel leaks

I think to show REM sleep you need a ZEO and then you import your ZEO data into Sleepyhead.

The ZEO reads brainwaves - and that is needed to determine what type of sleep stage you are in: deep, REM, etc..

I picked up my ZEO for about $100 delivered from Amazon. It links to my iPhone overnight and I download the CSV file from their website for later importing..

SleepyHead allows import of sleep stage data from the Zeo. If you don't have a Zeo there is nothing in SleepyHead that will give an indication of any sleep stage. Sometimes a loose correlation can be see between events and REM sleep if someone happens to have worsening OSA in REM sleep but it is not a definite thing and mainly seen by looking at normal sleep stages and comparing time line to your graphs.

Your PR S1 machine reports leak in a Total Leak L/min number. This means it includes the intentional vent rate plus any excess leak.

The % number shown on the machine itself...is % of time spent in large leak. Large leak seems to be around 90 L/min. I wouldn't want any % number at all.

If you are thinking that the leak number shown on SleepyHead is a % number....it isn't.
Instead the leak number is L/min... Don't try to compare your L/min number to someone with a ResMed report..their machines report only excess leak because the machine subtracts the vent rate before reporting.

Vent rate will vary with mask type and pressure used. Vent rate is shown in your mask literature by a graph...and as pressure increases the vent rate increases.

Example....At my average pressure the vent rate for my mask is around 35 L/min....the SleepyHead reports...you see the leak line go up and down....but final overall average might be 45 L/min....that is just 10 L/min over vent rate...it is an acceptable number.
Personally I don't look so much at the overall average leak number...instead I look at the leak line and just want to avoid large leak territory. If I avoid large leak territory the "number" takes care of itself.

I wouldn't be happy with an average leak number of say 60 L/min or above..that would mean that I spent more time up near large leak territory than I am comfortable with. Short lived spikes to large leak territory aren't the end of the world though.

So...if your mask vent rate at your average pressure happens to be 45 L/min..that is the starting point to evaluate leaks. It might seem high to you seeing the 45 number but it actually is normal for you.
I don't know which mask you are using nor the pressure..above number chosen as example.

Now if you are truly worried about the % of time in large leak number from the machine LCD screen....it takes a monstrous leak to show up as % of time in large leak and 0 % of time is large leak would be what I wanted. I think what you are seeing in SleepyHead is the L/min number and it is not the same thing as % number.

Hope this clarifies things, if not...tell me and I will try again.

I can very generally deduce REM from my ResMed S9 AutoSet respiration rate, tho like Pugsy says, it's a loose correlation and I know of this only because I have a Zeo, but I breathe more actively during REM as you can see in the chart below which shows Respiration Rate and I've matched up my Zeo sleep stages. This is only a rough indication in my case and I'm guessing your "sleep hygene" probably needs to be pretty "clean", that is... sleeping well. If one were waking all the time, tossing and turning would probably mess up the correlation.

Thanks Max and Pugsy....I'm off to look at my graphs and numbers to see if I can make heads or tails of it...I've recommended this site to 3 of my friends in last week...Once I posted on FB I was using CPAP they told me they do too...

Y'all rock!

MaxDarkside, your sleep stages look much better than what I see in my sleepyhead data every morning. I usually make it into the 3rd REM stage, after which I wake up and can't go back to sleep. It has only been 3 weeks on CPAP for me, so it could be I'm haven't adapted so well yet.

Can you say what the tall orange bars signify?

Can you say what the tall orange bars signify?

Thank you. Tall orange bars are "wake". Now days I tend to briefly wake up during REM in the later part of sleep. In those bars, I remember waking and looking at the clock and going back to sleep. There are really only 2 mid-sleep wakes there, the first one I had not fallen asleep yet and the last one I woke, checked the clock and got up.

Thanks for explaining!
