Sleep Study

Polysomnography (PSG), also called a sleep study, is a multi-parametric test used to diagnose sleep disorders. Polysomnography records your brain waves, the oxygen level in your blood, heart rate and breathing, as well as eye and leg movements during the study.

At Surgical Hospital of Oklahoma, our sleep studies allow our doctors to diagnose certain disorders such as sleep apnea, periodic limb movement disorder, narcolepsy, restless legs syndrome, insomnia, and nighttime behaviors like sleepwalking and REM sleep behavior disorder, in addition to multiple other abnormal conditions.

Once you are prepped for the test, the following steps occur:

Electrodes are attached to your scalp with a conductive paste to measure brain activity. This allows the technician to know if you are sleeping, and what stage of sleep you are in.
Electrodes are taped to your face near the eyes and chin to show muscle activity. These electrodes are used to measure eye movements, which also give clues to sleep stages, as well as chin movements which can observe possible nocturnal teeth grinding as well as other sleep disorders related to muscle activity.
Elastic belts are strapped around your chest and stomach to measure breathing effort.
Clear plastic tubing and a small monitor are affixed to measure breathing activity.
Electrodes are placed on each leg to measure body movement and muscle activity.
A monitor is taped to your finger to detect oxygen levels during the study.
A microphone is applied to your throat to detect any snoring.
