In this study, we propose a new method for assessing the blood flow of a compressed brachial artery using the loaded brachial arterial compliance and based on a two-element Windkessel (WK) model. The loaded compliance of the brachial artery has been estimated from the pattern of the oscillometric waveform in our previous study. The accuracy of WK-based mean blood flow (FWK) is validated by comparing it with the mean blood flow (Fecho) estimated by an echo-based method in the brachial arteries of 32 subjects. The results showed that the values of FWK and Fecho were significantly correlated (r = 0.671).
