About Microcirculation

The microcirculation is the final station for oxygen transport to tissues and plays a key role in the cardiovascular system [1]. It includes all of the vessels that are smaller than 100 micrometer in diameter and has a crucial role in blood and tissue interactions in terms of both physiological and pathophysiological states. Microcirculatory alterations are independent of systemic hemodynamic variables such as blood pressure, cardiac output and heart rate. Therefore microcirculation observations are a potentially important extension of conventional systemic hemodynamic monitoring of critically ill patients [2,3]. These findings have been made possible by our introduction of handheld microscopes to surgery and intensive care.
