Method for Pulmonary Administration Using Negative Pressure Generated by Inspiration in Mice

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...

Recurrent negative pressure pulmonary edema.

An African-American man, aged 34 years, underwent an elective uncomplicated right wrist laceration repair while under general anesthesia. Following extubation, the patient developed hypoxemia, tachypnea, shortness of breath, pulmonary rales, frothy sputum, decreased oxygen saturation, and evidence of upper airway obstruction. Chest radiograph showed pulmonary edema. The patient was diagnosed wi...
