Abstract:
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.
