[Pulmonary edema following airway obstruction].

This case report describes an adult patient who developed post extubation laryngeal spasm and later pulmonary edema following relief of the laryngeal spasm. The mechanism that causes pulmonary edema following upper airway obstruction is very probably due to a modified Müller maneuver (inspiration against a closed glottis), which will increase negative intrapleural pressure, and thereby cause increased pulmonary capillary permeability.
