Abstract：Objective To strengthen the quality and safety control of ventilator, so as to improve the stability of ventilator and reduce
its clinical risk. Methods FLUKE VT650 gas flow analyzer was used to detect the setting values, display values and measured values
of five parameters of the ventilator, including tidal volume, respiratory rate, oxygen concentration, inspiratory pressure level, and
positive end-expiratory pressure. Results Among the five parameters of 29 ventilators, the error pass rate of ventilation frequency,
tidal volume, inspiratory pressure level and positive end-expiratory pressure was 100%, and the oxygen concentration error pass rate
was 72.4%. Conclusion Most of the ventilators have been equipped with self-detection function, which can automatically complete
the testing and correction work. At the same time, the quality control of the ventilator can be regularly tested to improve its stability
and safety, and promote the safe and orderly development of medical work.
