Polysomnogram Study
Polysomnography, a type of sleep study, is a multiparameter study of sleep and a diagnostic tool in sleep medicine. The test result is called a polysomnogram also abbreviated PSG.
Titration Study
During the titration, the patient wears a mask and CPAP pressures are trialed up and down during sleep to find a single best pressure delivery and setting to control apnea events. Apneas can occur with different levels of severity during the varying sleep stages, body and sleeping position and other factors.
What is the purpose of a titration sleep study?
The sole purpose of a full-night study is
to calibrate the CPAP machine’s airflow rate
to the sleeper’s needs.
Split Night Study
This is a type of sleep study in which two night’s worth of recordings are combined into a single overnight observation.
Multiple Sleep Latency Test (MSLT)
In the multiple sleep latency test (MSLT), a person is given 4-5 opportunities to sleep every two hours during normal wake times. The specialist uses the test to measure the extent of daytime sleepiness (how fast the patient falls asleep in each nap, also called sleep latency), and also how quickly REM sleep begins.
