[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.
