Hello

My sleep study results came out and the index is 14.3 as it was 8 yrs ago.
Wonder why the heck that doctor didnt prescribe CPAP then.
Anyway... I had other things taken care of in my life in the last 8 yrs  
plus the CPAP equipment was probably not all that efficient 8 yrs ago.

My index is 14 (supine) and 0.6 (non-supine)

One thing they didnt explain and which I noticed after coing home is
the spontaneous arousals which is 169. What does it mean.
My total repiratory arousals is 35 and out of which 7 are apneas and
28 and hypoapneas.

Now even if I fix my apnea/hypoapnea with CPAP, do I have to be concerned
about the spontaneous arousals. I wonder why the doc didnt mention anything
about the spontaneous aropusals.

All I could read in in the internet was that spontaneous arousals are physiological and
do not disturb the sleep. If that is the case I still wonder why 169?.
I guess I have to go back to the doc and ask for
an explanation without offending them. She seemed very nice and proficient
and was also highly recommended by another specialist.

Also I read in one of the links in a post here that SPI (spontaneous arousal index)
is higher if AHI is higher. But in my case AHI is only 14 so I disagree with the
theory that SPI is related to AHI.

Forgot to mention that the A/C unit was right next to the  room where I slept and it bothered
me a lot. The tech told me after the study that my apnea didnt seem to be
high and that I woke up every time the A/C unit went on, but 169 times?

Also if I consider my non-supine results (just 1 event) I see no reason
to go for CPAP. I guess I need to treat my periodic leg movement and the spontaneous
arousal. Here again I disagree with the doctors decision to try CPAP.
I could sleep on my side and not be bothered by apnea or hypopnea.

Any input is appreciated

Those 169 sponaneous arousals may still be respiratory related.
Those may have been arousals caused by snoring or airway limitations,
but were not counted as apneas or hypopneas. I somehow
doubt that the A/C can be blamed for all those arousals.

An AHI of 14 seems mild, but it also depends on how long your
apneas hypopneas are. What was the lowest oxygen saturation?

lowest desat is 95%
mean SaO2 97.9 %
mean Wake SaO2 98%

Looks like they are high compared to others with apnea/hypopnea

I am very skeptical that CPAP will cure my sleeping problem

mupimohan - I also had a very high number of spontaneous arousals in my first study, around 100.

on CPAP, I had only 23...

As the other posted noted spontaneous arousals can be breathing related - UARS/Snoring events...  There is no good way to detect all of these so they can easily show up as spontaneous.
