Key result
Vasomotion analysis using the Periflux 6000 EPOS system revealed that changes in perfusion in myogenic, neurogenic, and endothelial frequency intervals precede changes in other microvascular signals.
Why the study?
Vasomotion facilitates microcirculatory gas and nutrient transport, but Laser Doppler flowmetry has so far constituted the gold standard for in vivo vasomotion analysis.

May enable earlier microvascular signal detection in research; leaves open clinical utility pending validation.
Observational (n=5)
The Periflux 6000 EPOS system enables novel aspects of microcirculation to be observed through vasomotion analysis of multiple physiological parameters.
Fredriksson et al. (2021) conducted an observational in Healthy (n=5). Vasomotion analysis using Periflux 6000 EPOS system was evaluated on Vasomotion signals (speed-resolved perfusion, oxygen saturation, RBC tissue fraction, average vessel diameter). Vasomotion analysis using the Periflux 6000 EPOS system revealed that changes in perfusion in myogenic, neurogenic, and endothelial frequency intervals precede changes in other microvascular signals.
