Sleep Tests

At Cone Health Sleep Disorders Centers, you and your doctor have access to a full range of sleep studies. These tests, which are monitored by a registered polysomnographic technologist™ (RPSGT), help your doctor confidently and accurately diagnose sleep disorders, including sleep apnea.

Polysomnogram (PSG)

Discover your sleep cycles and stages with a polysomnogram. You’ll wear small metal discs called electrodes on your head, soft elastic belts around your chest and belly, and a lightweight monitor on your finger or earlobe during sleep to allow your team to monitor physical activity such as:

  • Blood oxygen level
  • Breathing rate and air flow
  • Brain waves
  • Eye movements
  • Heart rate and rhythm

CPAP/BiPAP Titration

Your doctor may recommend a continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP) titration after a new diagnosis of sleep apnea, or if your symptoms have returned after using a CPAP or BiPAP machine for a while.

You’ll wear a mask connected to a CPAP or BiPAP machine while we monitor your sleep with a polysomnogram and find the right settings for optimal sleep for you.

Split Night Polysomnogram

This study combines a diagnostic polysomnogram with a CPAP study.

Home Sleep Apnea Test

If your doctor thinks you may have obstructive sleep apnea, ask whether you’re eligible for home testing. You’ll sleep in the comfort of your own bed while using portable polysomnogram equipment that collects information about your breathing. You may call our registered sleep technologist anytime during the night with questions or concerns.

Home sleep tests are available at Cone Health Sleep Disorders Centers at Annie Penn and Wesley Long. You can feel confident that you’re getting high-quality testing at home. The Wesley Long location is accredited in home sleep apnea testing by the American Academy of Sleep Medicine (AASM).

Multiple Sleep Latency Test (MSLT)

Detect how quickly you fall asleep in a quiet environment during the day with a multiple sleep latency test. You’ll spend all day at a sleep lab, and lay down for five scheduled naps separated by two-hour breaks. You’ll wear sensors that monitor your sleep stage. This test helps diagnosednarcolepsy.

Maintenance of Wakefulness Test (MWT)

Learn how well you can stay awake in a quiet, relaxing environment by taking a maintenance of wakefulness test. You’ll spend up to a day in the sleep lab and be asked to sit still for several predefined periods of time without falling asleep. In between wakefulness tests, you’ll be allowed to eat, watch TV or read.

Your doctor may recommend this test to evaluate the effects of your sleep disorder treatments or to help determine whether you can safely do your job.

Ask for a Referral

You’ll need a physician’s referral for a sleep study at a Cone Health Sleep Disorders Center.
