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...
متن کاملCapillary pressure and contact line force on a soft solid.
The surface free energy, or surface tension, of a liquid interface gives rise to a pressure jump when the interface is curved. Here we show that a similar capillary pressure arises at the interface of soft solids. We present experimental evidence that immersion of a thin elastomeric wire into a liquid induces a substantial elastic compression due to the solid capillary pressure at the bottom. W...
متن کاملNegative pressure pulmonary oedema after septoplasty.
Negative pressure pulmonary oedema (NPPO) is an anaesthetic complication due to acute obstruction of the upper airway, whose main cause is laryngospasm. The pathophysiology involves a strong negative intrapleural pressure during inspiration against a closed glottis, which triggers excessive pressure in the pulmonary microvasculature. Although its diagnosis can be difficult, its recognition help...
متن کاملSteam-Water Capillary Pressure
Steam-water capillary pressure is of central importance in geothermal reservoir engineering, however it is still poorly known due to the difficulty making direct measurements. To this end, we have conducted experimental and theoretical studies over the past five years and have made significant progress in understanding fundamental steamwater flow. In this paper, we summarize and discuss the res...
متن کاملEffective pulmonary capillary pressure.
The adult respiratory distress syndrome (ARDS) is almost invariably accompanied by permeability pulmonary oedema, usually appearing in the first few hours [1, 2]. The extent and therefore the seriousness of this oedema is proportional to the filtration of fluid and proteins through the pulmonary vascular endothelium. The extreme sensitivity of this filtration to variations of capillary pressure...
