Since his arrival, the sleep center has doubled its capacity and can serve patients six nights a week.Polysomnography is the big word for a sleep study, said Desta, who earned an associate’s degree in polysomnography/sleep technology in May 2011 at Johnson County Community College.“The overnight study monitors sleep and a variety of bodily functions during sleep,” Desta explained.
