A computerized system for occlusion pressure measurement during a rebreathing test is described. The system is implemented on an Apple II microcomputer. A set of programs allows calibration, data acquisition during the experiment, and fast automatic processing of the various parameters of ventilation and occlusion pressure versus end tidal PCO2. The use of a limited memory system is made possible by an electronic interface which allows preprocessing of the mouth pressure. In addition, that device drives a new simple electromagnetic valve with low flow resistance and dead space.
描述了一种用于重复呼吸试验期间闭塞压力测量的计算机化系统。该系统在苹果II微型计算机上实现。一组程序允许进行校准、实验期间的数据采集，以及对通气和闭塞压力与呼气末二氧化碳分压的各种参数进行快速自动处理。通过一个允许对口腔压力进行预处理的电子接口，使得在有限内存系统上的使用成为可能。此外，该设备驱动一种新型的简单电磁阀，其具有低流动阻力和死腔。
