A CLOSED LOOP SYSTEM FOR AUTOMATICALLY CONTROLLING A PHYSIOLOGICAL VARIABLE OF A PATIENT

摘要

The invention relates to a closed loop system for automatically controlling a physiological variable of a patient (1), with a measuring unit (3) for measuring a direct or an indirect value for the physiological variable of the patient (1), and an actuator (2) for treating the patient in order to affect the physiological variable. It is an essential feature of the invention that the actuator (2) is adapted for being controlled by the value measured by the measuring unit (3) and an additional value. Accordingly, a system for automatically controlling a physiological variable of a patient 1 in a closed loop is provided which is more efficient and reliable.
