Abstract

A pressure-corrected integrated flow plethysmograph allowing the study of mechanical characteristics of the ventilatory system during muscular exercise is described. In order to limit the increase in temperature inside the body box during exercise, a forced convective flow passes through the box. Thermal exchanges induced by this flow have been studied. They are sufficient to allow muscular exercise during 15 minutes at a constant power of 100 W. It has been verified that this type of box allows measurement of the usual parameters of ventilatory mechanics: pulmonary volumes, compliance, resistance using the panting method. The measurement of resistance during spontaneous breathing inside the box is not possible.

摘要

本文描述了一种压力校正集成流量体积描记器，可用于研究肌肉运动期间呼吸系统的力学特性。为了限制运动期间体腔内温度的升高，强制对流气流通过该体腔。对这种气流引起的热交换进行了研究。结果表明，这种热交换足以在100W恒定功率下进行15分钟的肌肉运动。已经证实，这种类型的体腔能够测量通气力学的常规参数：肺容积、顺应性、采用喘息法测量的阻力。在体腔内进行自主呼吸时无法测量阻力。
