Actigraphy
Wearing a small device that resembles a watch to record the continuous measurement of activity or movement as well as light exposure. This medical device is often used to assist in the management of sleep disorders, especially disorders and conditions that cause excessive daytime sleepiness (hypersomnia) or insomnia.
 
Generally, actigraphy devices can record data for 24 hours a day for about two weeks. They are useful in determining whether disruptions in the sleep-wake cycle exist. This information is then used to create a report showing active/ quiet times as well as light exposure.  Your provider will use this data in correlation with your symptoms, history and sleep testing if ordered.
 
CPAP/ BPAP Titration (In-Center Testing)
A sleep study for the purpose of adjusting your CPAP/BPAP machine. It typically comes after an in-lab diagnostic study. When possible, we try to perform the titration on the same night as the diagnostic study. In some instances where the diagnosis is not clear prior to your first sleep study, you will need to have a second titration study.
 
At times, your provider may recommend a re-titration sleep study.  This is to determine if your current prescribed therapy is still adequately treating your sleep disorder if symptoms reoccur.
  
Home Sleep Testing (Outpatient Testing)
A noninvasive, pain-free test that you do at home, in your own bed. A small medical device is worn during sleep for two consecutive nights. It records breathing patterns, oxygen levels and heart rate. Our highly-trained staff will show you how to use the device before you take it home and our doctors will review the information gathered and create a treatment plan.
 

 
Maintenance of Wakefulness Testing (MWT)
Measures how alert you are during the day. The test involves four sleep trials where you sit in bed and try to stay awake. Results of this test show how well you are able to function and remain alert in quiet times of inactivity. It also measures how well your sleep treatment is working. 
 
Polysomnogram (In-Center Testing)
A noninvasive, pain-free procedure that usually requires spending the night in a sleep room/sleep center. During a polysomnogram, a sleep technologist records multiple biological functions during sleep, such as brain wave activity, eye movement, muscle tone, heart rhythm and breathing via electrodes and monitors placed on the head, chest and legs.
 
After a full night’s sleep is recorded, the data is analyzed by a technologist and presented to a doctor for interpretation. Depending on the doctor’s orders, you may receive positive airway pressure therapy (CPAP/ BPAP) and/ or oxygen therapy during the night. Depending on the specific type of sleep study ordered, you may also stay after your overnight sleep study for further testing (MSLT-Multiple Sleep Latency Test).
