[Empirical Study on the Impact of Infusion Media on the Flow Rate of Infusion Pumps].

Objective: To investigate the impact of different infusion media on the flow rate of infusion pumps. Methods: Ten infusion pumps were randomly selected and tested for infusion rates using deionized water, saline solution, glucose solution, and parenteral nutrition solution. The infusion flow rate was set at 30 mL/h, and the testing methodology conformed to the standards for the calibration and quality control of syringe pumps and infusion pumps. Results: For infusion set A, the infusion rate was unaffected by the infusion media, remaining within the acceptable quality control standards. For infusion set B, when infused with deionized water, saline solution, and glucose solution, the infusion errors were within the quality control standards. However, when using parenteral nutrition solution as the infusion medium, the infusion error exceeded the acceptable quality control standards. Conclusion: Both the infusion set and the infusion medium can affect the flow rate of infusion pumps. It is crucial to calibrate the flow rate according to the specific infusion medium to reduce medical risks associated with infusion pumps during clinical use.

[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.
