I took an at home test through a buddy of mine that used to work at a local office. It monitored my breathing, heart rate, oxygen level and maybe other things. I had a hose in my nose, a sensor on my chest, a sensor on my stomach area, and the heart rate/oxygen sensor on my finger. It showed that i had about 20 episodes an hour (i think). As a result, “you’d feel better with cpap”. I use it every night.
