METHOD AND APPARATUS FOR DETERMINING AND/OR MONITORING A PHYSICAL CONDITION OF A PATIENT BASED ON AN AMPLITUDE OF A PRESSURE SIGNAL

摘要

A method for determining and/or monitoring quantities, in particular cardiovascular quantities, relating to a patient's condition, and an apparatus for measuring an amplitude of a cardiac pressure signal are disclosed. The amplitude of the pressure signal may be detected with the aid of a pressure sensor of a blood treatment apparatus, and its magnitude may be corrected by the contribution of the blood pump of the blood treatment apparatus so as to determine the amplitude of the cardiac pressure signal of the patient. The value of the amplitude of the pressure signal thus determined may subsequently be evaluated.
