Dr. Charles Mok explains the difference between obstructive and central sleep apnea and describes the WatchPAT device, a wrist-worn home test with FDA approval and common insurance coverage. It costs around $100 out-of-pocket if uninsured and works as well as lab sleep studies for most patients.

Obstructive sleep apnea and central sleep apnea are measured by a sleep study and traditionally had been in a sleep lab and now it's actually done at home with a device or something called the watch pat w a t C h like watch and pat P a t pulse amplitude technology that's FDA approved and commonly covered by insurance to measure your sleep at home and even your insurance uncovered is not very expensive just a little over 100 bucks device goes on your wrist like a watch and there's a sensor goes in your chest and a sensor goes in your fingertip and it gives us pretty much the same measurement. If somebody's relatively healthy they don't have of major obesity or major lung disease or heart failure or atrial fibrillation it works pretty much as good as a sleep lab. So this makes it much easier for doctors to diagnose sleep apnea because now it's not so cumbersome going to an expensive lab and something that a lot of people just don't want to do.
