Animal simulations extend microcirculatory oxygenation models; human validation required before any clinical relevance.
Effect estimate: 41-62% reduction
Diffusive interaction among red blood cells and capillaries significantly reduces capillary outflow saturation heterogeneity, aiding tissue oxygenation despite heterogeneous transit times.
Lücker et al. (2018) studied Healthy (mouse somatosensory cortex) (n=2). Diffusive interaction vs. Simulations excluding diffusive interaction was evaluated on Capillary outflow saturation heterogeneity (COSH) (41-62% reduction). Diffusive interaction among red blood cells and capillaries reduced capillary outflow saturation heterogeneity by 41 to 62% compared to simulations where diffusive interaction was excluded.
