Abstract

A system for obtaining respiratory flow rate waveforms, tidal volume, minute volume, respiration rate, inhalation time and exhalation time is described. The system is based on a microcomputer with analog-to-digital converter board. System software allows calibration, data acquisition and data analysis. Data can be obtained automatically at fixed time intervals. The system is inexpensive and reliable.

摘要

描述了一种用于获取呼吸流速波形、潮气量、分钟通气量、呼吸频率、吸气时间和呼气时间的系统。该系统基于带有模数转换板的微型计算机。系统软件允许进行校准、数据采集和数据分析。数据可以在固定的时间间隔自动获取。该系统价格低廉且可靠。
