Background
- Negative-pressure pulmonary edema (NPPE) ithat 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.
- Patients have and airway obstructive process either from an allergy, laryngospasm, trauma, and commonly in the case of hangings.
Clinical Features
Differential Diagnosis
Acute dyspnea

Evaluation
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
