Unique pathophysiologic changes during CPB result in pharmacokinetic alterations that impact the serum and tissue concentrations of IV and volatile anesthetics. CPB has evolved into routine, safe and reliable system that requires intensive specialized training to operate. It is the function of the perfusionist to maintain and operate this equipment during CPB; however anesthesiologist and surgeon caring for the patient undergoing CPB bear the responsibility of understanding this equipment and its function in order to manage the patient undergoing surgical procedure safely.
