摘要
从治疗呼吸衰竭的途径入手,提出了使用氦气和氧气混合气体的通气方式,介绍了基于ADuC848开发的氦氧循环通气装置,通过测量气路中压力、氧浓度、温度等信号,对氧气、氦气的输出实现PID控制,重点对通气装置中电子测控单元进行了详细分析。
From the treatment of respiratory failure, the method of breathing heliox is presented. This paper introduces the heliox-recirculating respirator based on ADuC848 which realizes PID control of heliox output through the measurements of the pressure in gas path, oxygen concentration, temperature and so on. The electronic measurement ＆ control unit is described in detail.
