Embodiment Construction

[0018] figure 1 One embodiment of a physiological monitoring device / system 10 for monitoring a subject 100 is illustrated. The monitoring device / system typically acquires a plurality of physiological signals 11 from the subject, where one physiological signal corresponds to one measurement channel. The physiological signals typically include several types of signals, such as ECG, EEG, blood pressure, respiration and plethysmographic signals. Based on raw real-time physiological signal data obtained from the subject, a plurality of physiological parameters may be determined, each physiological parameter calculated from waveform data of one or more of the physiological signals (acquired from the subject). If a physiological parameter is derived from several physiological signals, ie from several measurement channels, the physiological signals generally have the same signal type. The physiological parameter can thus also represent waveform signal values ​​determined over a pred...

Abstract

A method for generating alarms in a physiological monitoring apparatus, a physiological monitoring apparatus, and a computer program product for a physiological monitoring apparatus are disclosed. A quality measure is calculated (23) for a physiological parameter, the quality measure being indicative of confidence level of the physiological parameter. An alarm is detected (22) when the physiological parameter reaches a predetermined alarm limit and the alarm is escalated in response to the detecting, wherein the escalating includes conditionally raising priority of the alarm. The escalation of the alarm is controlled (24) based on the quality measure. (FIG. 2)

Description

technical field [0001] The present disclosure generally relates to patient monitoring. More particularly, the present invention relates to the escalation of alarms generated by physiological monitoring devices (hereinafter referred to as patient monitors). Here escalation refers to the process of scaling up an alert from a lower level of priority / severity to a higher level (if the alert persists and / or goes unacknowledged for a long enough time). Background technique [0002] Patient monitors are electronic devices designed to display physiological information about a subject. Electrocardiogram (ECG), electroencephalogram (EEG), plethysmographic signals, and signals related to blood pressure, temperature, and respiration represent typical physiological information contained in full-scale patient monitors. Patient monitors are also typically provided with an alarm function to alert caregivers when a patient's vital signs or physiological parameters exceed or fall below pres...
