WebJun 8, 2015 · Physiology. Resting splanchnic blood flow (SBF) is typically 30 ml min −1 100 g −1 of tissue, which equates to 25–30% of the cardiac output. This may decrease to <10 ml min −1 100 g −1 in low cardiac output states or peak locally at 250 ml min −1 100 g −1 after a meal. The splanchnic circulation must therefore be highly adaptive.
