Reading Sleep Study Results Identifying Sleep Apnea

This is a sleep study that shows someonewith sleep apnea. This channel right here shows a personbreathing 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 younotice every time they start breathing there's a big snort this is the source, then they stopbreathing, the big snort and they resume breathing. Another thingthat occurs

is oxygen fallsthat's the white channel, that goes down and then it comes up when they resumebreathing and it comes down so the oxygen is going up and down youcan see it best here. You can see it sliding up and down. Anotherthing 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 tobreathe

but they're not getting, they're notgetting any air. During the apnea, when they're notbreathing, the diaphragm is working and sucking thechest in, and you see the chest and abdomen go in differentdirections here and then, when they open their mouth and resume breathing, they start movingsynchronously again, they move together again and then when there's an apnea, they'removing in different directions again

That's one way you know that the apnea is an obstructive apnea.
