CTICasesNegative pressure pulmonary edema from endotracheal tube occlusion
Imaging findings
Chest radiograph in PACU shows extensive, symmetric central and perihilar alveolar consolidation with peribronchial cuffing, which resolved rapidly within 24 hours after relieving ET tube compression.
Key takeaways
Negative pressure pulmonary edema (NPPE) is a form of non-cardiogenic edema caused by strong inspiratory efforts against an obstructed airway (such as biting on an endotracheal tube during emergence from anesthesia). It characteristically presents with rapid onset and rapid resolution.
