Pulmonary edema is a potentialy life-threatening complication of acute airway obstruction. Occasionaly, patients experience sudden, unexpected and severe pulmonary edema during treatment of upper airway obstruction. Two forms of postobstructive pulmonary edema (POPE) have been identified. Type I POPE follows a sudden, severe episode of upper airway obstruction and type II POPE develops soon after the relief of chronic upper airway obstruction. The pathogenesis of POPE is multifactorial. The application of moderate continuous positive airway pressure in conjunction with the administration of diuretics usually clears pulmonary edema in these clinical settings within 24 hours. Awareness of this uncomon condition is crucial for the y edema after treatment for upper airway obstruction. (Korean J Otolaryngol 2002;45:1027-30)
