Frequently Asked Questions About Sleep Studies

What is a Sleep Study?

When you sleep your body functions differently than when you are awake. Daytime activities and health risks may be affected by disrupted sleep. Your physician has ordered a diagnostic test called a sleep study. During testing the length and quality of your sleep are measured and analyzed.

What do I need to expect?

Your test will be performed in a comfortable, private room. Youll be asked to complete a short bedtime questionnaire before changing into your nightclothes. A technician will attach small recording sensors/electrodes on your scalp, face, arms and legs. These electrodes don’t hurt and you can move freely while sleeping. You will not be given any type of sleep aid unless ordered by your physician.

You can read or watch TV until you’re ready for bed. An intercom will allow you to contact the technician to assist you with any needs. The technician will be observing you while you sleep through a small TV camera. This is necessary to record any movement during sleep.

 

What is recorded while I sleep?

  1. EEG or brain wave activity
  2. Eye movement
  3. Muscle movement
  4. Breathing pattern and effort
  5. Blood oxygen levels

Will I receive additional testing?

Occasionally, an additional test called a multiple sleep latency test (MSLT) may be necessary. If indicated, you’ll be asked to stay during the morning and afternoon and take several naps during this time. The technician will awaken you at the end of each nap. Generally, all testing will be completed by 4:30 PM. Should you be required to stay for additional testing, breakfast and lunch will be provided to you. If you’re unable to stay for further testing, please notify the technician in advance.
