  A sleep apnea monitor that was used on me a long time ago was based on
measuring the oxygen in the blood. It shined a red LED through the end of
my finger and an optical detector on the other side was able to measure how
red the blood in my finger was.

  The assumption being that Apnea would cut off breathing enough to make a
measurable difference. It worked rather nicely.

  It was a professional system, complete with a recording device to store
the measurements.

  So, while a sleep study at a sleep center gives much more meaningful data,
this was a "Take Home" device for a preliminary check for Sleep Apnea. I
suppose somebody could make their own, since it is not invasive, or pose any
risk to the user.
