Microcirculatory disturbances are known to affect the integrity of the gastrointestinal barrier. In our experiments, we aimed at characterizing the intramural microcirculatory reactions in response to various circulatory disorders using intravital microscopy with orthogonal spectral imaging technique. For the analysis and comparison of the microcirculatory reactions in the intestinal ileal mucosa, longitudinal muscle and Peyer's patches, a novel mathematical formula was established. ⋯ Systemic circulatory disorders are characterized by a non-uniform microcirculatory failure and a redistribution of blood flow between the different layers favouring the mucosa. Using the suggested mathematical formula, the microcirculatory alterations can be characterized and compared.
