HAEMODYNAMIC MONITORING DEVICE
First Claim
1. A device for haemodynamic monitoring, wherein the device comprises the following:
- reading in means for repeated reading in of data representing at least one physical variable,calculation means for calculating at least one parameter from the read-in data,calibrating means for calibrating the device, andtriggering means for triggering a calibration signal depending on the change over time of at least one of the the following;
the read-in dataat least one of the parameters.

Abstract
A relation is formed between an n-tuple having n components and formed at a first point in time and at least one other n-tuple having n components formed at at least one corresponding later point in time, wherein n is a natural number equal to or greater than 1, and the components comprise at least one derived parameter and/or one read-in data value. If this relationship satisfies a predetermined calibration criterion, a calibration signal is triggered and is displayed, and/or automatically triggers a recalibration of the haemodynamic monitoring device. For example, the pulse contour cardiac output PCCO is derived from the arterial pressure curve as the constituent component of a 1-tuple. As long as this differs from the reference cardiac output CORef by less than a predefined threshold value, for example 101 or 15% of the reference cardiac output, parameter determination continues without initiating a new calibration. On the other hand, if the deviation exceeds PCCO-COref I, the calibration signal is triggered.
