Sleep Fragments

A Quiz on Tracings 

Sleep Tracings is a monthly feature sponsored by the Respiratory Neurobiology and Sleep Assembly. Each tracing is in a question/answer format and is designed to test members' expertise in sleep medicine and polysomnography. The tracings may represent physiologic events, abnormal events, artifacts and sleep disorders. Tracings will come from both the adult and pediatric populations. Please come back each month for a new tracing. 

If you have a sleep tracing, sleep log or hypnogram that you would like to contribute, please contact James A. Rowley, MD at jrowley@med.wayne.edu
