The microcirculatory correlator: a new instrument for the intraoperative evaluation of visceral circulatory integrity.

The microcirculatory correlator probe has been used on multiple occasions on the abdominal viscera and clear pulse-wave tracings have been obtained from all the intra-abdominal organs. There is a linear correlation between deflection of pulse-wave and intestine blood flow in an isolated loop of intestine under low flow conditions. The probe has been used in two circumstances to good clinical advantage.
