How is the study performed?

During the CPAP study you are fitted with a nasal mask. The mask is connected by a tube to a small electric unit. The unit has a fan that pushes air through the tube. The mask allows the air to gently blow into the back of your throat. Pressure is started at a very low level. It is then increased at various intervals during the night. The goal is to find the right level of air pressure that will prevent the collapse of your upper airway. This eliminates pauses in your breathing as you sleep.

Home Sleep Test (HST) – HSTs offer the advantage of allowing testing in the patient’s own home and with less instrumentation, thereby theoretically providing a more natural sleeping environment.

The minimal number of sensors used during an HST limits home sleep testing to only be able to diagnose sleep apnea, while in-lab tests are able to identify and diagnose most sleeping disorders. Additionally the lack of a trained sleep technologist during home testing who, among other responsibilities, is able to recognize when a sensor has come off during the night and replace it while the patients sleeps, allows a greater potential for inaccurate tests and misdiagnosis.

Multiple Sleep Latency Test (MSLT) – The MSLT is an objective diagnostic tool that is used to measure excessive daytime sleepiness.  This test is performed during the day immediately following a nocturnal sleep study and consists of four or five 20-minute nap opportunities set two hours apart. During the test, data such as the patient’s brain waves, EEG, muscle activity, and eye movements are monitored and recorded. The entire test normally takes about 7 hours during the course of a day.

Maintenance of Wakefulness Test (MWT) - The MWT is a daytime sleep study that measures your ability to stay awake and alert during the day. The MWT can also tell your doctor how well your treatment is working. A MWT is usually done the day after a nocturnal sleep study and takes most of the day to complete.

PAP ADAPT – The newly developed United Sleep Diagnostics PAP ADAPT! Program is designed to assess and alleviate physical and emotional barriers to effective use of CPAP. PAP ADAPT! is a daytime program lasting from 2-5 hours which includes, a nap of 1 to 2 hours, hands on coaching (delivered by specially trained sleep technicians under the supervision of a physician) and same day feedback regarding the issues interfering with CPAP adherence. We will follow up with you to let you know the results of the patient’s progress in the PAP ADAPT! program.
