Sleep studies are most often performed on an outpatient basis at Portsmouth Regional Hospital, although some may also be conducted in your home. They're a simple, painless and effective way to diagnose and begin treatment for sleep disorders. Learn more about what to expect during your sleep study.
Our sleep center evaluates you for:
- Sleep apnea and excessive snoring
- Restless leg syndrome/periodic limb movements disorder
- Excessive daytime sleepiness
Types of Sleep Studies We Provide
Polysomnography (Sleep Study)
Once you're settled into one of our home-like rooms, our polysomnographic (sleep) technician will attach electrodes to your head, chest and legs to monitor nighttime sleep stages, respiratory airflow and effort and leg movements. Learn more about polysomnograms in our online Health Library.
Your sleep specialist may recommend that portable sleep monitoring be done in your home. A home care provider will teach you how to use the monitoring device and attach the sensors.
Continuous Positive Airway Pressure (CPAP)/Bilevel Positive Airway Pressure (BiPAP) Titration Studies
We may provide CPAP or BiPAP treatment. This involves placing a mask over your nose during sleep, providing pressure from an air blower that gently forces air into the nasal passages to improve breathing. If you are anxious about beginning CPAP or BiPAP, you may be able to do a brief nap study at our Sleep Center prior to an overnight study. This will ensure the mask fits properly and help you get comfortable using it. Learn more about CPAP at our online Health Library.
Multiple Sleep Latency Test (MSLT)
The MSLT consists of four to five naps, observed over an eight-to-ten-hour daytime period. An individual is given a 20-minute nap opportunity every two hours then instructed to stay awake between naps. Monitoring occurs throughout the test to record any sleep that occurs.
Maintenance of Wakefulness Test (MWT)
This test measures your ability to stay alert and awake, as opposed to how quickly you fall asleep. It helps determine how well you're responding to sleep disorder treatment and whether it's helping you overcome sleepiness. The MWT is conducted during the day and typically involves multiple sessions. It's required by the Federal Aviation Administration (FAA) for pilots and others in the transportation industry with sleep disorders.
Sleep Studies for Children
If you're concerned your son or daughter age six and up may be experiencing a sleep disorder, our sleep team will work with your child's primary care doctor to provide diagnosis and treatment.
Sleep studies and consultations are covered by most insurance providers. Please contact your individual health plan for pre-certification and referral requirements.
