Obstructive Sleep Apnea versus Central Sleep Apnea
Obstructive sleep apnea is when the airwaybecomes narrowed or obstructed and you're making the effort to breathe but we do notsee any flow in air movement coming from your nose or mouth. Where central sleep apnea occurswhere your brain forgets to tell your body to breathe. If we're looking at it from avery simplistic term and so we do not see the drive to breathe. So the first step isto come into the and be seen by one of our physicians in the sleep medicine .We'll go through a questionnaire and try to determine what risk factors we think you havefor sleep apnea such as obesity, snoring, daytime sleepiness and then if we think thatyou have a high risk for meeting those criteria
then we would set you up for a sleep studyeither in your home to do an overnight sleep study or in our laboratory, depending on yoursituation. The CPAP can be used to treat both conditions and, in some patients, that isenough. However, there are some patients that have more complex types of central sleep apneathat require more complicated types of machines to treat that condition. Obstructive sleepapnea actually has been linked to a lot of other problems such as high blood pressureand then, you know, difficulty functioning during the day. If it goes untreated for along period of time there's an increased risk of early heart problems and those types ofthings.
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.
