Polysomnographic Studies
There are 4 types of Polysomnographic Studies. They are:
Diagnostic Overnight PSG—General monitoring and evaluation.
Diagnostic Daytime Multiple Sleep Latency Test (MSLT)—Used to diagnose Narcolepsy and to measure the degree of daytime sleepiness. To ensure accurate results, it is performed on the morning following a Diagnostic Overnight PSG.
Two Night PSG with CPAP Titration Narcolepsy—General monitoring and diagnostic evaluation is conducted on the first night. 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 for CPAP Titration.
