An apparatus for generating biofeedback, in particular during a relaxation exercise for lowering blood pressure, comprises at least one interface for receiving a pulse wave signal that represents a pressure pulse or volume pulse of a pulse wave in a blood circulation system as a function of time and an ECG signal. The apparatus comprises an evaluation device that is configured to determine a pulse transit time on the basis of the pulse wave signal and the ECG signal, perform an evaluation of a pulse wave form of the pulse wave signal and generate the biofeedback depending on the pulse transit time and/or the evaluation of the pulse wave form. The apparatus comprises an output interface for providing the biofeedback.

Device, system and method for generating biofeedback

In a method for determining cardiac output from an arterial blood pressure curve measured at the periphery, in which the blood pressure curve measured at the periphery is arithmetically transformed into the corresponding central blood pressure curve and the cardiac output is calculated from the central blood pressure curve, the transformation of the blood pressure curve measured at the periphery into the corresponding central blood pressure curve is performed by the aid of an artificial neural network whose weighting values are determined by learning.
