| | #REDIRECT[[Negative pressure pulmonary edema]] |
| *Negative-pressure pulmonary edema (NPPE) occurs after a patient makes strong inspiratory effort against a blocked airway. The negative pressure causes hydrostatic edema that can be life-threatening if not but minimized if treated early, usually resolves after 24-48 hours. <ref>Bhattacharya M, Kallet RJ, Ware LB, Matthay MA. Negative-pressure pulmonary edema. Chest. 2016;150(4):927-33. </ref>

| *Patients have an airway obstructive process either from an allergy, laryngospasm, trauma, and commonly in the case of [[hangings]].<ref>Contou D, Voiriot G, Djibre et al. Clinical features of patients with diffuse alveolar hemorrhage due to negative-pressure pulmonary edema. Lung. 2017;195(4):477-487. </ref>

| ==Management==
| |
| *Remove any obstructive processes
| |
| *[[Intubation]] is often required
| |
| *Positive pressure ventilation
| |
| *Patients with severe pulmonary edema that do not respond to standard ventilator strategies may require proning or even [[ECMO]]
| |
| | |
| ==Disposition==
| |
| *Admission for continued monitoring often if not always in the ICU
