Patient monitoring system and method

Abstract

The present invention relates to a patient monitoring system (1). Further the invention relates to a method for monitoring a patient and to a computer program for a patient monitoring system (1). In order to provide a reliable technique for reducing the number of false alarms in a patient monitoring system a patient monitoring system (1) is suggested, which comprises a first sensor device (2) adapted to acquire (101) a first patient signal (10) corresponding to a first physiological parameter of the patient, a second sensor device (3, 4, 5) adapted to acquire (102, 103, 104) a second patient signal (11, 12, 13) corresponding to a second physiological parameter of the patient, said second patient signal (11, 12, 13) comprising an overlay signal (14, 15, 16) caused by the first physiological parameter of the patient, a processing device (7) adapted to determine (105) from the first patient signal (10) a first value of the first physiological parameter of the patient, to determine (106, 107, 108) from the overlay signal (14, 15, 16) of the second patient signal (11, 12, 13) a second value of the first physiological parameter of the patient, and to analyze (109) the first and second value of the first physiological parameter of the patient, and a control device (8) adapted to control (110) a patient monitor alarm system (9) depending on the result of the analysis.

Description

technical field [0001] The present invention relates to a patient monitoring system. Still further, the invention relates to a method for monitoring a patient and a computer program for a patient monitoring system. Background technique [0002] Patient monitoring systems are commonly used for observation of patient conditions in clinical settings. Currently, most of these patient monitors are multi-parameter patient monitors that can display a large number of different physiological parameters. [0003] One of the main tasks of modern patient monitoring systems is to alert medical personnel when one or more parameters show an unexpected (critical) behavior, or in other words, when a patient's physiological signal exceeds predetermined upper or lower alarm limits, i.e. Trigger an alarm signal. Although signal processing performance has been enhanced over the past few years, there are still a large number of false positive (single) alarms. These are alarms that are trigger...

AI Technical Summary

Problems solved by technology

However, these mechanisms were only developed for special cases (see refresh / sampling detection algorithm above)

There is no technique that is universal for other physiological parameters, or generally for a large number of physiological parameters

Additionally, use of these known algorithms may increase alert notification delays for true positive alert conditions

In other words, in the case of a true alarm, the alarm delay time is increased, which in some cases may harm the patient
