What does an in-lab sleep study (polysomnogram) look like?

Polysomnography, a type of sleep study, is a multi-parameter test used in the study of sleep and as a diagnostic tool in sleep medicine. It provides data that is essential in evaluating sleep and sleep-related complaints and problems. It measures your brain activity, oxygen level, heart rhythm, muscle activity and breathing pattern as you sleep. Sensors are placed on your head, face, chest and legs.

The sensors send tiny electrical signals to a computer to be recorded and reviewed. The signals show when you are asleep or awake during the night. The brain waves and eye movements can detect when you are in REM (dream) sleep or Non-REM sleep. The breathing-belt sensors show your breathing pattern or if you stop breathing during your sleep. Airflow and oxygen sensors are used to detect low air flow and changes in oxygen level.
