The flow-division mechanism at a bifurcation was studied experimentally in single asymmetrical bifurcation models with identical downstream impedances. Heterogeneous and asynchronous flow distribution under oscillatory conditions at high frequencies and with large tidal volumes were found. High-velocity inspiratory flow favors the pathway with the least directional changes. The results support the hypothesis that the convective momentum effects near a bifurcation produce heterogeneity and asynchrony of ventilation distribution.
