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.
目的: 探讨常规复用管路和一次性管路对呼吸机质控结果的影响。.
方法: 随机抽取17台呼吸机，分别采用常规复用管路和一次性管路进行质控，记录质控数据，然后采用配对 t检验分析2种管路的差异是否显著。.
结果: 对于呼吸频率、潮气量和气道末压，2种管路没有显著差异（ P＞0.05）；对于气道峰压，常规复用管路显著高于一次性管路（ P ＜0.05），但差异非常小，仅0.2 mbar（1 mbar=100 Pa）左右，不影响质控结论。.
结论: 常规复用管路和一次性管路不影响呼吸机质控结果，2种管路可以相互替代。.
