==Background==
*Also known as post-obstructive pulmonary edema
*Forced inspiration against obstructed airway causes large negative intrathoracic pressure, leading to pulmonary edema<ref>Bhaskar B, Fraser JF. Negative pressure pulmonary edema revisited: Pathophysiology and review of management. Saudi J Anaesth. 2011 Jul-Sep; 5(3): 308–313.</ref>
*Mostly due to postoperative laryngospasm, sudden drops in PEEP (high PEEP to manual BVM), trauma such as hanging, strangulation, foreign bodies, etc.

==Clinical Presentation==
*[[Hypoxemia]] (may be sudden and large - beware "fake" or "not real" SpO2), stridor, retractions, accessory muscle use, crackles/wheezes
*[[CXR]] shows diffuse interstitial and alveolar infiltrates
*CT shows preferential central/nondependent distribution of edema (as opposed to other forms of pulmonary edema)

==Management==
*Relieve airway obstruction
*Vent with generous PEEP and diuretics
