sleep report confusion

So its been almost a month and my sleep doctor hasn't told me my results or responded to my phone calls so i went and got them. I'm missing at least two parameters in the report and it seems less comprehensive than others I've read so I'm concerned and confused.

My current health issues are hypothyroid possibly with pituitary involvement, asthma, liver stenosis and some giant fibroids (upcoming surgery to remove those)) I had a neck injury awhile ago. My hypothyroid meds were too high the time of the study (and have since been dialed back). I do not have hashimotos - but no diagnostic on what kind yet.

This is my first sleep study. I seem to have a narrow airway now and wake up gasping and terrified or can't go to sleep because as i relax I can feel my throat closing before i fall asleep so i change positions of my neck and head. Whenever i get sick its especially difficult to breathe and it all gets so much worse going to the hospital has been considered at times. (btw - I do not snore, i am 100% positive of this. Nobody in my life at any point has ever heard me do so - I've asked them to listen for it.)

I'm concerned about the lack of heart results because i feel like it leaps around disconcertingly when i wake up bc i'm not breathing.
There was no mention of the leg movement results

I've seen other results that seem more comprehensive so I feel like some info is missing.

They also only listed my health issues as asthma and for some reason listed snoring as a past issue even though i told them i don't snore. I'm not sure if that impacted any interpretations

Here are the results.

study type PSG

Alice System was used. EEG, EOG, EMG were monitored for sleep staging. Nasal pressure, oro-nasal temperature, chest wall movement, abdominal movement, snoring and oxygen saturation were monitored for respiratory assessment.

Slept 293 minutes out of 455.2 minutes in bed for a decreased sleep efficiency of 65%.
The sleep latency was 100.1 minutes.
87.8% of the total sleep time was spent in the supine position
Stage N1 sleep was 7.7%
Stage N2 sleep was 38.6%
Stage N3 sleep was 30.2%

There were 57.70 minutes of wake after sleep offset
There were three REM sleep periods.
Stage R sleep was 23.5%
The stage R latency was 126.5 minutes

The overall apnea hypopnea index was 2.9 events/hr
The REM-specific index was 3.5 events/hour
The supine index was 3.8 events/hr
The obstructive apnea index was 0.0 events/hr

There were 13 obstructive hypopneas with a mean duration of 14.4 seconds
There was 1 central apnea with a mean duration of 10.0 seconds
The respiratory disturbance index, which unlinke the apnea-hypopnea index includes RERAs, was 2.9 events/hr
Mean saturation was 95%
90.8% of the study time was spent with a saturation in the 90-100% range
0.1% of the study time was spent with a saturation below 90%

There were 8 arousals related to respiratory events with an index of 1.6% arousals an hour
There were 64 Spontaneous arousals noted with an index of 13.1 arousals/hour. The etiology of some of these were unclear.

Due to artifacts in pulse collection maximum, minimum and mean heart rate data was compromised
The patient did display a normal sinus rhythm

Anything i should ask the Dr when i see them? Anything missing or unclear? Anything in particular for surgery prep?
Would anyone mind giving me some feedback on these results? Let me know if you need anything i didn't include.

So honestly, i was afraid to sleep on my back so it took me awhile to dig in and do it b/c waking up abruptly scares me and makes my heart do weird things. Unfortuntely i have no heart data b/c of "noise" and apparently no limb data either. I'm not sure how to count or interpret in all the hypopneas and wake events and spontaneous events. Should i redo this?
I have a surgery coming up and recovery is on my back which is extra concerning to me.
Thanks for any feedback. I will be talking to the doctor at the end of this week but it's been a month since the test, we haven't reviewed it yet and I'm trying to understand it to figure out what to ask him/be aware of.

If you feel your heart is of concern, since this test was unable to report on that, you could ask your doctor to order an overnight pulse oximeter or a period of time on a holter monitor. Also ask for the specifics on limb movements. Were your legs wired? Can't help but wonder that cause of all those spontaneous arousals. I'll let others more knowledgeable to weigh in on that. Don't know if UARS is at play or something else. Are you on any meds that could cause sleep problems?

If you spent all that time on your back (which provokes more apneas than any other position - they probably wanted a baseline scenario) and only got the hypopneas, you're doing great and may not need Cpap at all. I wonder if your thyroid (and/or meds) is more responsible for your symptoms if anything.

did a sleep study because going to sleep started becoming scary- just as i'd start to relax and fall asleep my throat would close and then I started walking up gasping or waking up rralizing I wasn't inhaling and it taking a second after with effort to inhale. Its new to me and scary.

The instant I get sick the apnea hyponea or whatever gets about 10x worse which was when I initially scheduled the study and became aware I had something going on. I don't snore, never have as far as I've been told by others.

The long onset sleep time is probably bc my hypo meds were too high and that's in the process of being fixed. It was also fear I'm sure. I used to love sleep but now it's a bit scary.

I don't have a heart issue that I know of, when I wake up gasping it's something that felt off and so wanted to see recorded data on and something I will get checked out separately.

I did have leg monitors attached.

All the spontaneous awakenings I'm guessing are bc of me reacting in my sleep to my throat relaxing before an event occurred but who knows since I don't have any leg or heart data to confirm or offer an alternative and haven't gotten my hands on the raw data...

I don't know how the info I have totals out in the breakdown like other reports I've seen contain and unless I math wrong there is a percentage of oxygen saturation data missing as well.

With all this data missing it's really frustrating.

If I missed any questions you all raised as I probably did but can't see from this window, I'll post them in another comment as I don't have access to the site yet and can't edit.

Thanks for responding. I do appreciate it.

You do have some oxygen data
You are correct it doesn't add up to 100%
90.8 % of the time
0.1% of the time
equals 90.9% of the time

I don't know that it necessarily means anything bad.
But it does make a person wonder where the other 9.1% of the time went.

Something you will have to ask your doctor about.

Have you read this. Might help clear up things a little bit.
