摘　　要：目的:研究呼吸机的氧电池实际使用时间与氧气体积分数测量误差的相关性。方法:分析呼吸机质量控制的现状,对比某院呼吸机近3 a质量控制检测结果,结合氧气体积分数报警故障处理案例,进行统计学对比分析。结果:呼吸机的氧气体积分数测量误差与氧电池使用时间呈近似线性相关性,氧电池启用430 d后的氧气体积分数测量误差会显著增加。结论:呼吸机氧气体积分数质量控制测量误差水平可作为氧电池性能评价及更换的重要参考依据。Objective To analyze the relationship between the measurement error of oxygen concentration and service time of oxygen cell of the ventilator.Methods The present situation of the ventilator was analyzed.Some cases of alarms for oxygen concentration failures were taken in statistical analysis on 3-a quality control detection results of the ventilators in some hospital.Results There was an approximately linear correlation between the measurement error of oxygen concentration and service time of oxygen cell, and the measurement error of oxygen concentration was increased significantly 430 days after the oxygen cell enabled.Conclusion The measurement error of oxygen concentration quality control could be used as a reference for performance evaluation and replacement of oxygen cell.
