在低呼吸率下,Pulmodyne全面罩 (PFFM) 显示出更好的患者呼吸器同步. 在更高的速度下,所有测试的全面罩在非侵入性正压通风过程中都表现类似.
科学领域:
- 呼吸机械学 呼吸机械
- 关键护理医学 关键护理医学
- 生物医学工程 生物医学工程
背景情况:
- 耳鼻口罩是非侵入性正压通风 (NPPV) 的标准,但会导致空气泄漏和不适.
- 整体全面罩是为了解决这些局限性而开发的.
- 缺少可用的全面罩的比较性能的数据.
研究的目的:
- 为了评估三种常见的全面罩对患者-通风器同步和压力支通风过程中的性能的影响.
- 为了比较Dimar全脸面罩 (DFFM),Performax全脸面罩 (RFFM) 和Pulmodyne全脸面罩 (PFFM).
主要方法:
- 使用连接到活跃测试肺部的模型进行长椅研究.
- NPPV应用了三种不同的全面罩.
- 分析患者 - 呼吸器同步参数,如 ΔPtrigger 和 PTP200/500 在不同的呼吸速率和吸气压力支水平.
主要成果:
- 在两种吸入式压力支 (iPS) 级别中,PFFM在20次呼吸/分钟 (RRsim) 时显著降低了ΔPtrigger.
- 在30RRsim时,DFFM显示了与RFFM和PFFM相比最长的ΔPtrigger.
- 与其他口罩相比,DFFM在所有通风器设置中具有显著较短的PTP200.
- 在面具之间没有观察到PTP500理想指数 (%) 的显著差异.
结论:
- 在较低的呼吸率下,PFFM提供了卓越的性能和同步性.
- 在增加的呼吸率下,测试的全面罩之间的性能差异会减少.
- 面具的选择可能取决于NPPV期间患者的呼吸率.

Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
