Negative pressure pulmonary edema is a well-known clinical condition mostly affecting young healthy adults and at times pediatric patients. It occurs mostly acutely in patients who have experienced airway obstruction. Most common pathophysiology is the development of a negative intrathoracic pressure which results in increased preload and subsequently increase pulmonary hydrostatic pressures. The pulmonary edema develops once the airway obstruction is relieved and the forces opposing the transudation of fluid into the interstitial tissues are removed. Management includes a high index of suspicion in patients who have developed airway obstruction, early recognition, relief of obstruction, and maintenance of airway along with oxygen therapy. BIPAP or CPAP may be needed in patients who do not responds to these measures. Invasive mechanical ventilation with high FiO2 is reserved for refractory hypoxia.
