Abstract

A method and system for adaptively controlled withdrawal/infusion of a fluid, such as blood, to or from a fluid source, such as a blood vessel. An adaptive flow rate limit is established and periodically adjusted during the course of withdrawal/infusion so as to maximize and optimize the withdrawal/infusion rate while, at the same time, providing for rapid corrective adjustments in flow rate responsive to early indications of flow disruption, such as occlusion or collapse of the blood vessel during blood withdrawal. The method and system of the invention is particularly applicable to automated apheresis systems.
