In the US, diagnosis is made in a one-night sleep clinic with an EKG and an adjustable CPAP. If you do this, make sure to tell the technician that if you register apneation, you would like a CPAP titration calibration done immediately. This saves you (a) another bad night's sleep in the clinic and (b) insurance hassles.

Then you go back to your doctor, discuss your need for a CPAP or APAP machine right now, and possible longer-term treatments.

Depending on insurance specifics, it may be much cheaper to buy a CPAP from an online source than via a full-service insurance-covered medical equipment company. Saving 50-75% is not unusual.
