摘　　要：目的对机械通气过程中呼出潮气量的不同测量方法的测量精确度进行比较。方法使用呼吸机测试仪与流量测定仪对不同测量方法的几种呼吸机进行测试。结果不同测量方法测得的结果偏差较大,机械通气呼出潮气量近端测量精准度优于远端测量。结论对于呼出潮气量的测量精度,流量传感器置于病人气道是最有效的手段,越靠近病人测量得的精度越高。Objective To compare the measurement accuracy in different methods of measuring exhaled tidal volume in ventilating.Methods To test these ventilators uses different measuring methods of exhaled tidal volume by using ventilator tester and flow locator.Results There is a big measurement deviation among the different measuring methods of exhaled tidal volume.The measuring accuracy of the near end in mechanical ventilation exhaled tide volume is better than that of remote end.Conclusion For exhale tide volume measurement precision,to put flow sensor in the patient airway is the most effective method.The measurement accuracy is better if sensor is close to the patient.
