Polysomnograms Des Moines IA

Polysomnograms (PSGs) are performed at special sleep laboratories with academic or hospital affiliation, or in independently located and operated facilities. Sleep labs are often set up to resemble a bedroom, in order to help participants feel at ease. A sleep technician hooks patients up to the monitoring and recording devices, and then monitors the patient throughout the study. If a problem is noted, a second sleep study will be schedule to determine the best method of delivery.

I f the sleep technician confirms that you have sleep apnea in the early part of the night you may have what is called a ‘split-night study' (half diagnosis, half titration). After about 4 hours of observing how you sleep, the technician will wake you up to initiate CPAP (continuous positive airway pressure). While on CPAP, the technician will continue to monitor you and measure the effectiveness of this treatment. This process can be done over two full nights in some cases.
