What is a hospital based sleep study?

An overnight sleep study or polysomnography (PSG) is a non-invasive test that is performed when the presence of a sleep disorder is suspected. All sleep studies are conducted in a private room and do not cause any pain or significant discomfort.

Prior to going to sleep, sensors are placed on the head, face, chest, stomach, legs and fingers. These sensors are kept in place with medical tapes and pastes. Throughout the night, sleep scientists monitor:

  • Brain wave activity
  • Respiration
  • Eye movement activity
  • Heart rate
  • Muscle tone
  • Blood oxygen level.
