(from the Atlanta Journal-Constitution, via Drudge) A 25 year old man recently died during a sleep study at Emory:
Harris, a medical assistant, entered the Emory sleep center on Jan. 22, said his mother....... By the next morning he was dead.
Emory said in a statement that he died of sudden cardiac arrest....
The article doesn't give many details and doesn't specify whether Mr. Harris was having a diagnostic study or a CPAP titration study.
Usually the most dangerous part of a sleep study is the drive to the sleep center.
