Research on the Quality Control of Routine Reusable Pipeline and Disposable Pipeline of Ventilator

Objective To explore the effect of routine reusable pipeline and disposable pipeline on ventilator quality control results.

Methods 17 ventilators were randomly selected to conduct quality control using routine reusable pipeline and disposable pipeline respectively. Quality control data were recorded and then paired t-test method was used to analyze whether the difference between the two pipelines was significant or not.

Results There were no significant differences in respiratory rate, tidal volume and end airway pressure between the two types of pipes (P＞0.05). The airway peak pressure of routine reusable pipeline was significantly higher than disposable pipeline (P＜0.05), but the difference was very small, only about 0.2 mbar which would not affect the conclusion of quality control.

Conclusion Quality control of ventilator is not affected by routine reusable pipeline and disposable pipeline, which can be replaced by each other.
