I finally went and had a sleep study done after years of my wife having to endure my snoring. Of course, once she told me that I would stop breathing from time to time, I didn’t walk, I ran to the sleep clinic. There are different ways to perform sleep studies, my insurance only covered a one night study. Once at the clinic, the technician hooked up various sensors used to record the ‘before’ measurements and then I went to sleep. At least I tried to.
After I slept about half the night away, the tech woke me so she could put a CPAP (I know it looks like CRAP right?) or Continuous Positive Air Pressure mask on me, like so:
Then I tried to sleep the rest of the night as they recorded all my vitals etc. while I had a machine blowing air in my face the whole time. They should call it a ‘not getting any sleep’ study.
A couple of weeks later at the follow-up appointment, the doctor showed me the before and after results of all that monitoring that went on. She pulled out this rather cool looking chart of things like blood pressure, oxygen levels and the different levels of sleep I attained that night. My brain waves provided the data. All very sophisticated and scientific.
Then the doc points out one particular set of lines on the graph and says, “Look at how many fewer arousals you experienced after we put the CPAP machine on you.” Well I stopped and stared at her for some time and said, “I didn’t even realize you were measuring that.” She then gave me a long stare back and said, “It means how often you almost woke up.”
Crickets.
“Oh”, I said, “so that’s what that means.” And then I left.
