Abstract

A simple method of measuring the pressure exerted by the cuff of an endotracheal tube on the trachea is described and has been used to measure the pressures exerted by 16 commercially available cuffs on the wall of a model trachea. The Shiley, Portex soft-seal, Kamen-Wilkinson (Bivona Fome) tubes had the lowest tracheal wall pressures. Using this method in vivo the changes in tracheal wall pressure exerted by a low-pressure cuff during percussion and vibration physiotherapy, and when the patient "fights the ventilator", were recorded.

摘要

本文描述了一种测量气管内导管套囊对气管施加压力的简单方法，该方法已用于测量16种市售套囊对模型气管壁施加的压力。希利（Shiley）、波特克斯软密封（Portex soft-seal）、卡门-威尔金森（Kamen-Wilkinson，比沃纳泡沫（Bivona Fome））导管的气管壁压力最低。使用该方法在体内记录了在叩击和振动物理治疗期间以及患者“对抗呼吸机”时低压套囊施加的气管壁压力变化。
