Abstract
Using a digital computer and body plethysmograph measurements of airways resistance, lung volumes, and flow-volume loops may be obtained from a single manoeuvre performed by the patient. All the measurements together with a display of the flow-volume loop are displayed within 10 seconds of the patient completing the manoeuvre. The system appears to offer considerable advantages in speed, objectivity, and reproducibility when compared with conventional methods.
摘要
使用数字计算机，通过人体体积描记法测量气道阻力、肺容积，并可从患者执行的一次动作中获取流量-容积环。在患者完成动作后的10秒内，所有测量值以及流量-容积环的显示都会呈现出来。与传统方法相比，该系统在速度、客观性和可重复性方面似乎具有相当大的优势。
