It has saved my brother’s life. And I mean that literally.
When I got my Apple Watch I downloaded a sleep monitoring app and discovered I spent most of the night “awake”. This convinced me to do a sleep study.
The results came back that I was having over 90 “episodes” of apnea an hour, with a fair percentage of the “central” as opposed to “obstructive”.
Obstructive is just as it sounds. Your airway gets obstructed and cuts off breathing. Not good.
Central is worse. If you have central apnea it means that your brain is forgetting to breath.
Both types can kill you, but central apnea freaks the doctors out a bit.
I have been using my CPAP for over a year now. It reports to an app so I can see each morning how effective it was. My obstructive apnea is all but eliminated. Central is still an issue, but the CPAP keeps me from dying.
