This study represents the validation of an out-of-laboratory recording system for screening sleep disorders by comparing it to an in-laboratory system which accomplishes complete polysomnography. Forty patient cases were collected. Each patient slept in the sleep laboratory with the simultaneous monitoring of eight channels from the Sleep I/T (CNS, Inc), as well as complete polysomnographic monitoring comparable to that which accomplishes routine patient evaluations utilizing the Sleeplab (CNS, Inc) system.

Fourteen patients with chronic obstructive pulmonary disease (COPD) and chronic hypoxemia were studied to evaluate the relationship between hypoxemia and objective and subjective daytime sleepiness. Patients were selected with a waking PaO2 of less than 70 mm Hg and less than 50 percent predicted FEV1. Clinically, none of these patients had complaints of significant daytime sleepiness.
