Abstract
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.
