摘要

一种新的流量调节PEP装置在功能和压力特性方面进行了评估。方法在标准流速为10和18 L/min时，对3种不同的阻力水平进行评价；采用Kruskal-Wallis试验分析不同阻力水平产生的压力差异。结果在10和18 L/min的气流下产生3 ~ 31 cmH2O。在两种流量下，不同阻力水平下的压力有显著差异。综上所述，在两种流量下，不同阻力水平下的压力存在显著差异，高阻力比低阻力显著增加压力。这种新器件的性能可与市场上现有的其他电阻器相媲美。

Pressure Properties of a New Positive Expiratory Pressure Device—OpenUp Flow a Three-in-One Solution

Introduction

A new flow-regulated PEP device has been evaluated regarding functionality and pressure properties.

Methods

The three different resistance levels were assessed and evaluated at standardized flow rates of 10 and 18 L/min; Kruskal–Wallis test was used to analyse the differences in generated pressure between the different resistance levels.

Results

A range of 3–31 cmH₂O was generated with airflows of 10 and 18 L/min. There was a significant difference in pressure among different resistance levels at both flow rates.

Conclusion

Overall, there was a significant difference in pressure among different resistance levels at both flow rates, showing that the high resistance significantly increased pressure compared with low resistance. This new device is performing comparable with other resistors available in the market.
