A sleep study or polysomnogram (PSG) is a test that electronically transmits and records specific physical activities while you sleep. The recordings are sent out to a medical service for analysis by a qualified sleep specialist registered with the College of Physicians and Surgeons of Alberta.
There are four kinds of sleep studies, including:
Diagnostic overnight PSG: General monitoring of sleep and a variety of body functions during sleep, including breathing patterns along with oxygen levels in the blood, heart rhythms, and limb movements
Diagnostic daytime multiple sleep latency test (MSLT): The MSLT is used to diagnose narcolepsy and to measure the degree of daytime sleepiness. It measures how quickly you fall asleep in quiet situations during the day. It also monitors how quickly and how often you enter REM sleep. To ensure accurate results, it is performed on the morning following a diagnostic overnight PSG.
Two-night evaluation PSG and CPAP titration: CPAP (continuous positive airway pressure) is a sleep apnea treatment that involves the delivery of air into the airways through a specially designed nasal mask. On the first night of the two-night protocol, general monitoring and diagnostic evaluation is conducted. If sleep apnea is discovered, the patient returns for a second night to determine the necessary CPAP pressure required to alleviate apnea.
Split-night PSG with CPAP titration: Split-night PSG is conducted when moderate or severe sleep apnea has been discovered or strongly suspected during the first part of the night's study. The second half of the night is used to determine the necessary CPAP pressure required to alleviate apnea.
Remmers Sleep Recorder
Merrell Clinic uses the Remmers Sleep Recorder, which records diagnostic indicators of sleep apnea and is used to follow up on the titration of oral appliances and monitor the effectiveness of CPAP therapy. This sleep recorder has a proven reputation and track record of validated test results.
