【摘要】 Datex—ohmeda Aestiva/5 7100型麻醉呼吸机的使用时间长了以后,出现潮气量误差大(超过±10%)的现象,引起潮气量过低报警,主要与麻醉呼吸机的压差型流量传感系统有关。该流量传感系统由流量传感模块和监测控制模块组成。传感器测得的信号送至监测控制模块,由监测控制模块根据每次呼吸的频率、气体的流量计算出每分钟潮气量。更多还原

【Abstract】 Datex-ohmeda Aestiva/5 7100-based use of anesthesia ventilator a long time after the error appears large tidal volume(more than±10%) of the phenomenon,caused by low tidal volume alarm,mainly related to the pressure anesthesia ventilator type flow sensor system.The flow sensing system by the flow sensor control module and monitoring module.Measured sensor signals to the monitor and control module,control module by monitoring the frequency in accordance with each breath,the gas flow meter to calculate the tidal volume per minute.更多还原
