摘要

垂流是指空气在肺部区域之间的流动，EIT 已显示出探测和监测垂流的能力。在本说明中，我们提出了一种功能性 EIT 测量方法，可量化垂流中出现的反向气流：反向阻抗变化分数 (FRIC)。FRIC 测量每个像素波形（作为图像）或全局（作为单一参数）中的反向气流比例。这种测量方法比以前的方法更加具体，可以对垂尾进行比较研究，并有助于明确通气策略的效果。

Fraction of reverse impedance change (FRIC): a quantitative electrical impedance tomography measure of intrapulmonary pendelluft.

Objective. Pendelluft is the movement of air between lung regions, and electrical impedance tomography (EIT) has shown an ability to detect and monitor it.Approach.In this note, we propose a functional EIT measure which quantifies the reverse airflow seen in pendelluft: theFraction of Reverse Impedance Change(FRIC).MainResults. FRIC measures the fraction of reverse flow in each pixel waveform (as an image) or globally (as a single parameter).Significance. Such a measure is designed to be a more specific measure than previous approaches, to enable comparative studies of the pendelluft, and to help clarify the effect of ventilation strategies.
