Well, I got the results of my study and it says "diagnosis: normal sleep study." However, if this is normal then I wonder why everyone isn't falling asleep all day like me!

It recorded a total sleep time of 344 min, during which according to the Sleep Fragmentation section I had 185 arousals - 32.3 per hour. Is that "normal?"

the results were as follows:
Total sleep time: 344 min
Sleep efficiency: 76.3%
sleep latency: 67 minutes
obstructive apnea: 0
mixed apnea: 0
central apnea: 1
hypopnea: 29

Total AHI 5.2
NREM AHI: 3.7
Stage R AHI: 13.5
Supine AHI: 6.6
Non-Supine AHI: 3.1
4% Index: 0.3 (What is this??)
Min Sa02: 93%
Baseline Sa02: 98%

WASO: 39 min
Stage N1: 9.9%
Stage N2: 56.7%
Stage N3: 17.9%
Stage R: 15.6%
Stage R Latency: 216 minutes.
Stage W: 104 minutes (???)

First of all, what the heck is the 4% Index and Stage W? I've never heard of these terms.

I realize that many of these values are normal or close to normal, but to me it seems like the arousals, Sleep latency and Stage R latency are pretty out of whack. Shouldn't this warrant some kind of interpretation other than "normal sleep study?" I can't stay awake for more than 3.5 or 4 hours without the aid of a stimulant medication. I fall asleep all day long, and apparently at night my sleep is fragmented at a rate of more than once ever 2 minutes. How can that be interpreted as normal?
