Objective To explore the factors affecting the quality control qualification rate of invasive ventilators in our hospital and corresponding corrective measures.Methods Firstly,conduct a risk assessment of the ventilator and develop a preventive maintenance and quality control testing plan based on the assessment results.Using the Fluke gas flow analyzer VT650 as the detection tool,key parameters such as tidal volume,ventilation frequency,inspiratory oxygen concentration,inspiratory pressure level,and positive end expiratory pressure of our hospital's invasive ventilators were detected,and the set values,displayed values,and measured values were recorded(data selected from the detection records of the first half of 2024).Results Among the 71 ventilators tested,40 ventilators were found to have non compliant items,mainly due to the low qualification rate of tidal volume and inspiratory pressure levels.After maintenance and calibration,the qualification rate of each parameter has increased to 100%,and the overall qualification rate has also increased to 100%.Conclusion Regular risk-based invasive ventilator quality control management can effectively improve its stability and safety.However,there is a large deviation in the error rate of tidal volume output value,so more efforts should be made to maintain it,thereby promoting the safe and orderly development of medical work.
