摘要

To monitor supply to a vessel during dialysis treatment, pressure is monitored in both arterial (5) and venous (7) branches of extra-corporeal blood circulation by means of pressure sensors (18,19). The sum and the difference of the two pressures are input to a computer (22) used to calculate characteristic values for the state of supply to a vessel. These values are processed in an evaluation unit to identify errors in supply to a vessel.
