Method for determining cardiac output
First Claim
Patent Images
1. A method for determining cardiac output from an arterial blood pressure curve measured at a peripheral region, comprising the steps of:
- measuring the arterial blood pressure curve at the peripheral region;
arithmetically transforming the measured arterial blood pressure curve to an equivalent aortic pressure; and
calculating the cardiac output from the equivalent aortic pressure, whereinthe arithmetic transformation of the arterial blood pressure curve measured at the peripheral region into the equivalent aortic pressure is performed by the aid of an artificial neural network having weighting values that are determined by learning.

Abstract
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.
