Three definitions are useful for the sleep study.
Apnea. The Greek word “apnea” means “without breath.” You stop breathing during sleep for ten seconds or longer.
Hypopnea. There is airflow through your throat but at a much reduced level, which leads to not getting enough oxygen. It’s abnormally shallow breathing lasting at least ten seconds.
AHI, Apnea-Hypopnea Index for Obstructive Sleep Apnea:
Less than 5 events (apnea or hypopnea) per hour is considered normal.
5 or more events per hour is considered Mild
15+ considered Moderate
30+ considered Severe (from T. S. Johnson MD, Sleep Apnea - The Phantom of the Night, page 211)
A sleep study uses a pulse oximeter, a device with a red light that clips on your finger. It measure oxygen levels in your blood by noting the color; oxygenated blood is bright red, blood with hemoglobin desaturation is darker red.

Tips for Wearing a Mask and Using CPAP for the First Time
• Expect elaborate headgear, face straps, and stiff, bulky plastic nose pieces that make you look like an astronaut.
• While the sleep technician puts the mask on you, breathe through your mouth.
• Before you are hooked up to the CPAP machine, ask the technician to let you feel the airflow from the hose on your hand. It’s surprisingly breezy. It will feel much less breezy when felt through a mask.
• You won’t need it, but to make you more comfortable psychologically, ask the technician to show you how to quickly remove the mask and how to disconnect the mask from the hose or CPAP machine. The technician will show you how to call him or her during the night.
• While sitting up, spend a few moments “practice breathing” through the mask with CPAP turned on. It works! You can do it. You can even fall asleep while wearing it.
