Postobstructive pulmonary edema.

Pulmonary edema is a potentially life-threatening complication of acute airway obstruction. It develops rapidly, without warning, in persons who are otherwise well. Two forms of postobstructive pulmonary edema (POPE) have been identified. POPE I follows sudden, severe upper airway obstruction. POPE II occurs following surgical relief of chronic upper airway obstruction. Treatment for both is supportive. Full and rapid recovery can be expected with appropriate management.
