- electrodes to measure my brain waves and stages of sleep (there are 3 plus REM)
- movement sensors on my legs, arms, and parts of my face
- a heart rate monitor
- belts on my chest and tummy to measure movement when I inhale and exhale
- a microphone
- a nasal cannula
- a second measuring something or other under my nose
- an oxygen saturation probe on my finger
They monitor and watch, collect a ton of data, wake you up at 6a, rip off all the wires, tell you basically nothing, and send you on your way.
I did sleep off and on. I woke up whenever there was noise in the hallway -- usually to hear someone tell the guy in the room across the hall to roll over or to change out his mask. You think they'd do a better job of soundproofing a sleep clinic! The guy should probably have his own county. Maybe he does. I can't imagine neighbors, dogs, cats, goldfish, or wild animals putting up with the ruckus. Amazing!
And I can tell you exactly where the monitoring room was in proximity to my room because well, the sleep techs don't sleep at night, they talk.
This week, they'll put on a lot of the same sensors and then go through having me sleep -- or try mightily -- with a series of CPAP (continuous positive airway pressure) masks to see if they prevent the apnea spells and contribute to better sleep -- actual consistent breathing, oxygenation, deeper stages of sleep, REM, etc.
I can't imagine being able to sleep with a freakin' Hannibal Lechter-esque mask on my face, but we'll see what happens. (I almost included a photo of a mask in this post, but very quickly closed the google image search results because the pix were freaking me out...)
If nothing else, I predict a craving for fava beans will strike sometime tomorrow.
