After wearing the sensor for two nites I returned to the dentist's office whereupon he told me I had awakened 32 times (a hour?) the first night and 28 times the second nite.
He advised me to get a ResMed S-9 Escape, Quattro mask and the heated humidifier.
I did. I don't notice that I sleep any better. BUT! I no longer need to take a nap after eating breakfast.
After that affirmation I will now go for a sleep study. I may end up with a ResMed S-9 Elite as that seems to furnish more information to the user.
