Data Source: A retrospective cohort study to assess the association between sleep-disordered breathing and adverse pregnancy outcomes in150 women who had a delivery and an in-laboratory polysomnogram
between January 2000 and June 2009.
The definitive test for OSA is an overnight polysomnogram
performed in a certified sleep laboratory.
Sleep apnea is typically diagnosed with an overnight sleep test called a polysomnogram
Catathrenia: a rare parasomnia which may mimic central sleep apnea polysomnogram
is a test which measures a variety of signals using electrodes placed on your scalp before you fall asleep.
A nocturnal polysomnogram
is the standard test to diagnose sleep apnea.
revealed extremely severe obstructive sleep apnea, and the patient's apnea/hypopnea index (AHI) was 94 events per hour; he experienced 561 apneas over a 6-hour period of sleep.
Patients suspected of having OSAS should undergo polysomnogram
testing in an approved sleep laboratory.
Subject protocols consisted of an 8-hour polysomnogram
followed by 2-hour units during which the patients evaluated their subjective vigilance, provided salivary samples, had a free walk period, and then were confined to a reclining chair.
One of the most important tests is generally a nighttime polysomnogram
, a non-invasive measurement performed in a pediatric sleep-apnea laboratory.
During his polysomnogram
he proceeded to masturbate the whole night, clearly seen on the videotape.
These problems together with the lack of ability to get very precise, repeatable results make the laboratory polysomnogram
defective as a 'gold standard'.
