Sleep study

Comprehensive sleep evaluations tell the story of your nighttime rest

If your provider is unable to make a diagnosis based on information you provide about your sleep habits, he or she may refer you for a sleep study. This type of evaluation can provide a detailed picture of your sleep patterns.


What is a sleep study?

A sleep study, or polysomnography, is an overnight test that allows our experts to monitor your sleep stages and cycles. This makes it easier to identify if or when your sleep patterns are disrupted. The overnight observation is done in a private room at one of our sleep centers. These rooms are similar to hotel rooms, with private bathrooms and showers attached.

Measurements taken while you sleep include:

  • Brain activity
  • Sleep duration
  • Airflow
  • Eye movements
  • Breathing efforts
  • Leg movements
  • Muscle tone
  • Heart rate
  • Blood oxygen levels

This study provides a noninvasive, painless evaluation of your sleep. Our sleep center teams are available to ensure your stay is pleasant and to answer any questions you may have.

When participating in a sleep study, you will typically arrive around 8 p.m. and will be awakened around 6 a.m. the following morning. If you need to make different arrangements, we can work with you to schedule a time that is more convenient.

Other sleep tests

During the sleep study, your care team may conduct several additional tests, such as:

  • Multiple sleep latency test - This test measures the severity of daytime sleepiness using a series of five, 20-minute naps given every two hours throughout the day.
  • Continuous positive airway pressure (CPAP) - If the initial polysomnogram suggest a significant breathing disorder, CPAP is sometimes used to treat the disorder. CPAP is a method of delivering the necessary air pressure through a nasal mask, which maintains an open airway during sleep.

If you or someone you care about is suffering from insufficient sleep, call one of our sleep medicine locations to schedule an appointment with a sleep expert today.
