How Can We Help?
In-Lab Sleep Study Or Polysomnography
Your doctor may have suggested undergoing In-Lab Sleep Study or Polysomnography (PSG). This is used to diagnose sleep disorders like sleep apnea, insomnia, and narcolepsy among others. These disorders cannot be readily identified during your first consultation with your sleep specialist thus require additional tests to confirm them.
PSG is an overnight exam that is usually done in the sleep center. This test monitors your brain waves, breathing patterns, and heart rhythms during your sleep. Your body movements and eye movements are also recorded. The data gathered through this test will help your sleep specialist in the diagnosis, treatment, and management of your condition.
