Partners may complain of restless sleep, periods of apnea. Daytime sleepiness, depression, unrefreshing sleep, etc. are not specific and may occur with other sleep disorders, depression. Women with obstructive sleep apnea may be thin and have small neck circumference.
Menstrual irregularities are common.
Expensive and time consuming but is the gold standard. 5 or more episodes of apnea per hour. Continuous nocturnal oxygen saturation measurement at home. Not valid in those receiving oxygen therapy. Can use to screen before ordering sleep study, since it has a high negative predictive value and is inexpensive.
