这项研究评估了六种非侵入性通风 (NIV) 设备,发现飞利浦三联Evo/EV300和汉密尔顿C3表现最好. 虽然NIV设备可以处理空气泄漏,但患者的精力很低,肺部阻塞模式也很困难.
科学领域:
- 呼吸系统护理 呼吸系统护理
- 生物医学工程 生物医学工程
- 肺部医学 肺部医学
背景情况:
- 随着COVID-19大流行,对呼吸机的需求增加,对新的和现有的非侵入性通风 (NIV) 设备的兴趣增加.
- 缺乏可靠的证据来比较不同临床场景中不同NIV设备的性能.
- 将适当的NIV设备与患者的需求和护理环境相匹配,对于有效的治疗至关重要.
研究的目的:
- 为了对六种非侵入性通风装置的性能进行基准测试.
- 在体积传递,触发响应,加压能力和同步方面比较设备的有效性.
- 在模拟的生理条件下评估设备的性能,包括不同的泄漏水平,灵感力度和呼吸模式.
主要方法:
- 利用ASL5000®肺模型模拟36种不同的实验条件.
- 通过触发延迟时间测量评估触发功能.
- 使用压力-时间曲线下的面积评估压缩能力.
- 通过异步指数和对异步类型的分析量化同步.
主要成果:
- 所有测试的NIV设备总体表现良好,尽管加压能力低于预期.
- 设备功能没有受到模拟空气泄漏的显著影响.
- 观察到表现的变化,特别是在低吸气肌力和阻塞性呼吸模式的条件下.
- 菲利普斯三部曲Evo/EV300和汉密尔顿C3在测试参数中普遍表现出优越的性能.
结论:
- 非侵入性通风设备有效地弥补空气泄漏,但在帮助低吸气力或阻塞性肺部疾病的患者方面存在局限性.
- 了解非侵入性通风的具体目标对于临床医生在选择设备和设置关键参数时至关重要.
- 优化设备选择和参数设置是实现成功的非侵入性通风治疗结果的关键.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
