Study on Calibration method for ventilatorsJIANG Xue-ping, SHAO Lei Hangzhou Institute of Technology Testing and Calibration,Hangzhou 310004, ChinaAbstract:The accuracy of ventilators has heavy impact on medical treatment, it is urgent for clinical work to set up a perfect ventilator calibration method and calibrate it periodically with it. On the basis of many experiments and many systematically tests of various ventilators, one reliable calibration method has been established for ventilators, which is scientific, reasonable, and easy to use. The evaluation result of each indicator can satisfy the requirements of the designing performances and measurements for ventilators. Thus this method can provide certain guidance to calibrate ventilator for medicine clinical and legal metrological verification institutions.[著者文摘]
