Sleep Study results

Post by Cr1kk1t » Thu Dec 15, 2016 9:34 pm

Hi everyone,

I got the results of my sleep study yesterday.I can't say that I understand it. I am being put on an Aircurve 10 ST with the settings of 20/10 and a backup rate of 12. I have been diagnosed with complex sleep apnea. Here are the results of my study. if you want more info, just ask and I will post it.

TRT: 545.5 minutes
TIB: 514.5 minutes
TST: 410.0 minutes
Sleep Efficiency: 79.7%
Sleep Onset: 0.0 minutes
Waso: 104.5 minutes What is this???
Rem Latency from sleep onset: 68.0 minutes

Stages:
N1: 18.5 min TST 4.5% Latency from sleep onset 13.5 minutes
N2: 237.5 min TST 57.9% Latency from sleep onset 13.0 minutes
N3: 66.5 min TST 16.2% Latency from sleep onset 0.0 minutes
Rem: 87.5 min TST 21.3% Latency from sleep onset 68.0 minutes

Worst AHI was 114.3/hr at 19/8
<89% O2 230.4 minutes of that 213.5 minutes was in NREM.
# of Destats TST: 186
No limb movement
All apneas were CA and Hypopneas. And the majority were in NREM. And oddly enough when I was laying on my side.

Still disappointed they didn't do the MSLT but I guess that is ok as I have enough to deal with at the moment.

So can someone explain all this to me? You would think after 5 sleep studies I would understand this but... I don't. lol

WASO is Wake after sleep onset I think

Robysue has some basic "what does the sleep study say" in her blog. Check it out and see if there's anything she doesn't cover that you don't understand.
http://adventures-in-hosehead-land.blog ... -test.html

Sleep stages percentages. I am not real up on all of them but the REM % is pretty much normal if I remember right.
Google "sleep stages" and you can read up on how much in each stage is normal.

REM Latency is how long it took to get to the first REM stage...and normal is around 90 minutes so yours is a little sooner but still not all that bad.

Are you still living at a higher altitude?

Start with this and then if that doesn't help, there have been numerous definitions posted on the forum over the years.

Hi Pugsy,

Yes I am still in Colorado. May be moving to Idaho or Montana in a couple of years.
Thanks for all the info. I will look at the blog.
I forgot to mention that I still have to use 3L of oxygen at night. No matter what pressure they used they couldn't get my sats up without it. The doctor doesn't know why my sats still dip despite the Bipap.

Hope all is well with you.

I am doing well thank you for asking.
I remember you. A real puzzle for sure. I have often wondered how you might do if you weren't at the high altitude.
You are getting a great machine and it should serve you well.

You might read up on narcolepsy and those MSLT tests. From what little I understand about them they look for not only rapid sleep onset but also if REM sleep is sudden also.
If it were me I wouldn't have wanted the MSLT immediately after the sleep study anyway. I never could understand why they would do a sleep test after a sleep test where there was a real good chance the person might not have slept well. Seems like it would taint the MSLT. If it were me I would want it done after a good night's sleep.
I think keeping the MSLT on the back burner for now is probably an acceptable alternative. Revisit it after you have been on the new machine for considerable time. With your centrals there's a good chance that once they are effectively dealt with that you may not continue to have the symptoms that prompted the MSLT discussion.

Does the Aircurve work with Sleepyhead?

I changed my setting on my current machine to 20/10 until I get the new one. But I am having a huge issue with dry mouth and throat to the point I wake up gasping for air and rip the mask off. I have the humidifier set to max and there is also humidity with the oxygen. Kinda frustrated with it.

A puzzle I am. The two sleep doctors I have been working with keep shaking their heads. lol Despite compliance with therapy I am still extremely sleepy during the day. The only way I can survive the day is to take Modafinil and even then it's not enough. The sleep doc just upped it to 1 pill in the morning and 1/2 a pil after lunch. Of course now I have been diagnosed diabetic as well so that throws a wrinkle in things too. I think I am starving to death.... And I will be starting allergy shots in January.

Is it too much to ask to just not be so sleepy all the time???

SleepyHead works well with the regular AirCurve machines but I don't know about that special model that you are getting.
All you can do is try it an see.

Check your leak report to see if it is showing very much leak. Dry mouth is usually a symptom of some mouth breathing going on.
Now it may not take much mouth breathing to dry the mouth out but you should check the leak graphs to make sure it's not enough to harm the therapy.

I've been using my full face mask an airfit F10 that I normally use when I am sick in hopes that it would help but nope.

Dry mouth from mouth breathing is a common complaint even with a full face mask and even with the machine cranking out maximum humidity. It simply can't produce enough moisture to re hydrate the mouth adequately. It was designed to help moisturize the nasal cavity and not the oral cavity.

If it becomes too annoying you may have to do what a lot of other people do which is use some sort of product designed to help restore moisture to the mouth.

Why some people and not others have such a big problem with dry mouth?? Who knows. Maybe they take some other meds that tend to dry out the mouth or maybe they just are unlucky.

I have Dry mouth issues and my DR recommended XyliMelts

I purchased a box of 40 to try from Wal-mart for around $8 and they do seem to help in my case.

Hi Cr1kk1t:

I have desat problems at altitude (>5000 feet) but fortunately I live closer to sea level. As a result, I don't fly any more.

Have you been checked for any lung issues that could contribute to the lower SpO2 values that you are seeing? I suspect that mine is affected by my very mild COPD.

I suspect that the air is dryer where you live and that lots of extra humidity will be required.
A few of us have moved to additional humidification using external sources.
Link to external humidifier design:
Here is my setup to solve this problem.

On longer night nights (>8 hours), I use all of the water in both water chambers and that is more than twice that of the Respironics alone.

One of my sleep doctors is also a lung specialist and the only issue with my lungs is my asthma and it is only illness induced.

I live in a very dry area and never empty the humidifier overnight. Most nights it is still half full. Hopefully when I get the new machine next week things will improve. I'll look into those xylomelts to see if they help.

When you get the new machine make sure and get the heated hose.
With the heated hose you can more control over maximum humidity delivery to at least get as much moisture as possible from the humidifier.
You can set the humidity and the hose air temperature independent of each other. That's what I do. I choose maximum humidity delivery year round and the only thing I change is hose air temp. Warmer for the winter months and cooler during the summer.
