What is a Sleep Study?

A sleep test, called polysomnography is usually performed to diagnose sleep apnea.

There are 2 kinds of polysomnograms.

An overnight polysomnography test involves monitoring brain waves, muscle tension, eye movement, respiration, oxygen level in the blood and audio monitoring (for snoring, gasping, etc.).

The 2nd kind of polysomnography test is a home monitoring test. A sleep technologist hooks you up to all the electrodes and instructs you on how to record your sleep with a computerized polysomnograph that you take home and return in the morning.

They are painless tests that are usually covered by insurance.
