Abstract

Obstructive sleep apnea is a condition characterized by recurrent upper airway collapse during sleep, which may be associated with sleep disruption and repetitive oxygen desaturations. It is diagnosed by nocturnal in-lab polysomnography or home sleep apnea testing. We present a case of an otherwise healthy individual who had home sleep apnea testing that revealed persistent, unexplained hypoxemia which, on further investigation, was found to be due to a saddle pulmonary embolism.
