Abstract:Objective To develop a VBA semi-automatic management system to perform the quality control of invasive ventilators in
our hospital. Methods Under volume preset ventilation mode, regular inspections and quality control of the invasive ventilators in the
hospital were conducted. Test items included electrical safety, tidal volume, respiratory rate, oxygen concentration, etc. A recording
and statistical tool of quality control data of ventilator was designed and developed using VBA,and the quality control results were
analyzed quantitatively. Results Regardless of oxygen battery failure, the pass rates of ventilator tidal volume, respiratory rate, I/E
ratio, inspired oxygen concentration, positive end expiratory pressure, and electrical safety were 96.79%, 99.28%, 99.64%, 95.36%,
98.24 % and 100%, respectively, with a complete qualified rate of 93.49%. Considering oxygen battery failure, the qualified rate of
ventilator inspired oxygen concentration was 78.38%, with a complete qualified rate of 73.45%. Conclusion Regular quality control
and preventive maintenance is one of the most effective means to improve the safety and effectiveness of ventilators, and also an
effective way to reduce ventilator-related adverse events.
