瑞典西门子公司生产的伺服900型呼吸机以使用简便、功能齐全系统、稳定性好。900C、900B呼吸机的故障绝大多数发生在气路部分。本文将其常见故障与检查方法作一简介。检查时,面版各参数置标准位(有绿色色彩档),一般出现气源报警或工作压力摆动超过170Pa(5cm·H_2O)就要作必要的检查,但应以不影响每分钟通气量为前提。一气源不足:摘下空氧混合器后,用改锥轻触混合器块速接头的出气阀,能听见急而短的爆破声,表明压力是足够的。反之,气流声较缓则表明供气不足或气源衰竭。其原因通常为:
The Servo 900 ventilator produced by Siemens in Sweden is easy to use, fully functional, and stable. Most of the 900C and 900B ventilator malfunctions occur in the airway section. This article will give an introduction to its common faults and inspection methods. During the inspection, the faceplate parameters are set to standard position (having green color file). Usually the air source alarm or working pressure swing exceeds 170Pa (5cm H2O), the necessary inspections should be made, but the minute ventilation should not be affected. premise. Insufficient air supply: After taking off the air oxygen mixer, touch the gas outlet valve of the mixer block speed joint with a screwdriver, and you can hear the rapid and short blasting sound, indicating that the pressure is enough. On the contrary, slower airflow sounds indicate insufficient air supply or air failure. The reason is usually:
