Abstract

Computerized instrumentation and software have been developed to obtain maximum expiratory flow-volume (MEFV) and partial expiratory flow-volume (PEFV) curves. The computerized system calculates and prints out the flow at 25% and 40% of control vital capacity (VC), the expiratory volume, peak expiratory flow rate and expiratory volume at one second (FEV1) divided by VC, the latter expressed as a percent. The flow-volume curves can be displayed on an oscilloscope or plotter and stored on magnetic tape. A pilot study was completed to demonstrate the reliability and validity of the data obtained.

摘要

已开发出计算机化仪器和软件来获取最大呼气流量-容积（MEFV）和部分呼气流量-容积（PEFV）曲线。该计算机化系统计算并打印出控制肺活量（VC）的25%和40%时的流量、呼气容积、呼气峰值流速以及一秒钟呼气容积（FEV1）除以VC的值，后者以百分比表示。流量-容积曲线可显示在示波器或绘图仪上，并存储在磁带上。已完成一项初步研究以证明所获得数据的可靠性和有效性。
