A method, a system and an arrangement for predicting at least one system event and a corresponding computer program and a corresponding computer-readable storage medium are configured so that it is possible to predict a system event based on trends in observables over a certain period of time prior to the event occurring. One example of a system event is the failure of a system because the abnormal behavior of a component is reflected in irregularities in one or a plurality of observables. Another example of a system event is the early recognition or pre-acute prediction of a specific critical condition of a patient.

Method and arrangement for predicting at least one system event, corresponding computer program, and corresponding computer-readable storage medium

The invention relates to methods and systems for determining phase-specific parameters of a physiological variable, and a related computer program and a related machine-readable storage medium, which are usable in particular to determine parameters of physiological variables that are subject to circadian variation. To this end, phase-specific parameters of a physiological variable X(t) are determined by calculating, at least for a portion of values x lying in a specifiable time period, a mean g(x|&#x3c4;) in each case of values X(t+&#x3c4;) for which X(t)=x applies for their predecessors, &#x3c4; describing a time interval, and determining the phase-specific parameters by evaluating the mean g(x|&#x3c4;).

Determining phase-specific parameters of a physiological variable

A monitoring apparatus having a signal input for signals representing measurement values of one or more physiological parameters, and an evaluation and processing unit connected to the signal input. The evaluation and processing unit is designed to select, or differently weight, individual values from the values received for further processing based on one or more criteria such that measurement values raising doubts as to the validity thereof are not selected or given a very low weighting.

Apparatus and method for processing physiological measurement values

Embodiments relate to a heart monitor, which is connected to or can be connected to at least one sensor for pressure and volume data or equivalent substitute variables and which comprises an evaluation unit for processing at least one input signal reflecting the temporal course of pressure and volume data or equivalent substitute variables of the heart. The evaluation unit is configured such that it segments the input signal in accordance with individual completed cardiac cycles and examines segments of the input signal obtained in this way as to whether a particular segment of the input signal represents a PV diagram, which corresponds to specified quality conditions regarding the direction of circulation, morphology and distance between a starting and end values.

Heart monitor

A method, a system and an arrangement to predict at least one system event and a corresponding computer program and a corresponding machine-readable storage medium are configured so that the event is predictable because of trends in observables over a certain period before the occurrence of the events. The method, system and arrangement can be used in particular for patient-specific monitoring of patho-physiological changes but also in geophysical or abstract units such as population or economic systems in which the deviation from a defined normal condition is predicted.
