This is a sleep study that shows someone
with sleep apnea. This channel right here shows a person
breathing and then they stopped breathing for what seems like a long time it's about 40 seconds and then they breathe again, they wake up,
and they stopped breathing again and then they breathe again, and you
notice every time they start breathing there's a big snort this is the source, then they stop
breathing, the big snort and they resume breathing. Another thing
that occurs is oxygen falls–that's the white channel, that goes down and then it comes up when they resume
breathing and it comes down so the oxygen is going up and down you
can see it best here.
You can see it sliding up and down. Another
thing to note his when they're not breathing their chest and abdomen will move. This one here is chest in this down here is abdomen, so they're still trying to
breathe but they're not getting, they're not
getting any air. During the apnea, when they're not
breathing, the diaphragm is working and sucking the
chest in, and you see the chest and abdomen go in different
directions here and then, when they open their mouth and resume breathing, they start moving
synchronously again, they move together again and then when there's an apnea, they're
moving in different directions again That's one way you know that the apnea is an obstructive apnea.
