A sleep study or polysomnography is a diverse test which is used to diagnose the following disorders related to sleep.

Sleep Apnea

Lowered oxygen levels in your blood during a sleep study may mean that you have sleep apnea.

Insomnia and Sleepwalking

Insomnia can be identified with the patient not being able to fall asleep. Sleep walking will make the patient able to walk without being conscious. The brain is conscious during sleep walking, but you are physically in a trance-like state. This can be identified by the brain activity sensors.

The different equipment used in a sleep study or polysomnography are:

  • ECG, also known as electrocardiogram, is used to record heart rate and rhythm.
  • EEG, also known as electroencephalogram, is used to track the brain activity.
