概括
新的呼吸功能监测器 (RFMs) 在新生儿复苏过程中显示的准确性与旧型号相美. 在高泄漏条件下,自充气袋的性能下降,但T片复苏器保持了准确性.
科学领域:
- 新生儿复苏术 新生儿复苏
- 医疗器械技术 医疗器械技术
- 呼吸系统生理学 呼吸系统生理学
背景情况:
- 国际复苏联络委员会 (ILCOR) 目前不建议用于新生儿复苏的呼吸功能监测器 (RFM).
- 较新的,紧的RFM提供了更好的便携性和临床集成.
- 之前关于RFM共识的研究使用了复杂的,仅用于研究的设备.
研究的目的:
- 为了比较两个新一代RFM与两个传统RFM的准确性和性能.
- 在各种强制性的动态泄漏条件下评估性能 (0-90%).
- 用不同的通风装置来评估准确性:自充气袋 (SIB) 和T片复苏器 (TPR).
主要方法:
- 四个RFM (两个新一代,两个传统) 被测试.
- 强制实施0%,20%,50%和90%的动态泄漏.
- 手动通货膨胀被运送到一个试验肺使用SIB和TPR.
- 每个RFM测量了潮体积,泄漏和压力,并与参考值进行了比较.
主要成果:
- 所有RFM都表现出了与潮体积,泄漏和压力在零泄漏时的可比准确性.
- 所有测试的RFM在所有泄漏水平上都准确地测量了系统泄漏.
- 在90%的系统泄漏时,RFM测量的体积与SIB显著减少 (<50%的无泄漏体积).
- 在90%的泄漏率下,TPR交付的数量表现出较小的影响,并且比SIB交付的数量更准确.
结论:
- 新一代RFM的精度和性能可与传统设备相提并论,即使在大量泄漏条件下也是如此.
- 所有测试的RFM都准确地检测到高达90%的系统泄漏.
- 与高泄漏水平的SIB相比,RFM性能显著下降,与TPR不同.
- 新一代RFM的简化用户界面可能会提高临床可用性.
