Negative pressure pulmonary hemorrhage induced by asphyxia

Negative-Pressure Pulmonary Edema.

Negative-pressure pulmonary edema (NPPE) or postobstructive pulmonary edema is a well-described cause of acute respiratory failure that occurs after intense inspiratory effort against an obstructed airway, usually from upper airway infection, tumor, or laryngospasm. Patients with NPPE generate very negative airway pressures, which augment transvascular fluid filtration and precipitate interstit...

Negative pressure pulmonary oedema.

EDITOR: Negative pressure pulmonary oedema is a medical emergency that usually arises from attempted ventilations against an acutely obstructed upper airway, such as the one that occurs during laryngospasm, resulting in transudation of fluid from pulmonary capillaries to the interstitium. Frequently, this occurs in the perioperative period when general anaesthesia is used. Clinicians should pro...

ExERCISE-INDUCED PULMONARy HEMORRHAGE

Exercise-induced pulmonary hemorrhage (EIPH) occurs in horses that race at high speeds, such as Thoroughbred and Standardbred racehorses. The disease is almost unknown in endurance horses or draft breeds. As a general rule, the more intense the exercise or higher the speed attained, the greater the proportion of horses with EIPH. The prevalence of EIPH varies with the method used to detect it a...

Negative pressure post-tracheal extubation alveolar hemorrhage.

N egative pressure pulmonary edema is an uncommon complication of extubation of the trachea (>0.1%) mostly caused by laryngospasm (1). Upper airway obstruction from glottis closure leads to marked inspiratory efforts, which generate very negative intrathoracic pressure. This may cause pulmonary edema (1,2) and, rarely, hemoptysis (3,4). This report is the first to document both bronchoscopic an...
