Rest comfortably in a private room while we assess your sleep disorder

For patients at the St. Charles Sleep Center, your sleep physician will first determine if you need a sleep study, also called a polysomnogram. If you do need a sleep study, you'll arrive in the early evening, stay the night and leave the next morning. You'll sleep in a private room, and we’ll monitor your body functions overnight.

Sleep study tests

While you're resting, we're working to determine what's disrupting your sleep. We'll place painless electrodes on the surface of your scalp, face, chest and lower legs. The electrodes will measure:

  • Blood oxygen levels
  • Brain waves
  • Breathing effort and movement
  • Eye movement
  • Heart rhythms
  • Leg movements

We can then use the information we've collected to help diagnose your sleep disorder and create an individualized treatment plan that gets you a good night's rest.
