Objective:To collect and analyze the quality control data of ventilator, so as to apply these statistical data to guide the maintenance and management of ventilator.Methods: The displayed value and monitoring value of the tidal volume, respiratory frequency, inspiratory oxygen concentration, inspiratory pressure level and positive end expira tory pressure (PEEP) under different setting of 50 using ventilators in hospital were collected by using PF-300 gas analyzer, and then each parameter was analyzed as classification.Results: The total quality rate of ventilators was 80%, the ranking of quality rate as different brand was: brand B>brand A>brand C, and it was as different department: department 5>department 4=department 3>department1>department2, and the quality rates of less than 3 years and more than 3 years were 87% and 77%, respectively, as service life of ventilator. And the ranking of quality rates as parameters of ventilator was: PEEP=respiratory frequency >peak pressure>tidal volume >oxygen concentration. It was as accuracy of monitoring: brand A>brand C>brand B. It was as stability of monitoring: brand A>brand B=brand C. On the other hand, it was as the accuracy of displayed value: brand A>brand B>brand C, while it was as the stability of displayed value: brand A>brand C>brand B.Conclusion: The analysis of quality control data only suits to the ventilator which is used in our hospital. The engineer can targeted to strengthen the ventilator maintenance work and improve the quality and safety of equipment, so as to give the better service for patients according to quality control data of using ventilators in hospital.%目的:对医院在用呼吸机质量控制数据进行采集分析,将得到的统计数据用于指导呼吸机的维护管理.方法:使用PF-300型气流分析仪对医院在用的50台呼吸机采集潮气量、通气频率、气氧浓度、吸气压力水平及呼吸末正压(PEEP)在不同设置值下的示值和测试仪示值,并进行分类单项分析.结果:医院在用呼吸机整体合格率为80%,按品牌合格率排名:品牌B>A>C;按科室合格率排名:科室5>科室4=科室3>科室1>科室2;按呼吸机使用期限:<3年的合格率为87%,>3年的合格率为77%;按呼吸机参数合格率:PEEP=呼吸频率>峰值压力>潮气量>氧浓度;按监测值准确性排名:品牌A>C>B;按监测值稳定性排名:品牌A>B=C;按显示值准确性排名:品牌A>B>C;显示值稳定性排名:品牌A>C>B.结论:根据医院在用呼吸机的质量控制数据情况,工程师可有针对性的加强对呼吸机的维护保养工作,提高设备的质量与安全,更好的为患者服务.
