Negative-pressure pulmonary edema (NPPE) occurs when a large, negative intrathoracic pressure is generated against an obstructed upper airway, causing fluid to shift into the lung interstitium.

The iron lung used negative pressure ventilation (NPV), which “mimics natural breathing by creating negative pressure around the chest, causing the lungs to expand and pull in air,” explains ...

Objective: This study aims to investigate the drainage effect and clinical outcomes of negative pressure chest drainage in patients after two-port thoracoscopic valve surgery, comparing the ...
