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

Embodiment Construction

[0040] figure 1 A patient monitoring system 1 according to the invention is illustrated. Monitoring system 1 as described suppresses false positive apnea alarms related to respiration (eg caused by motion artifacts or noise signals) by using the patient's invasive blood pressure signal as an alternative parameter.

[0041] The system 1 comprises a plurality of measuring electrodes 2 adapted to perform impedance respiration measurements to obtain a respiration signal 10 corresponding to the patient's respiration, see figure 2 . The system 1 also comprises a measurement device 3 for sensing the patient's invasive blood pressure (PAP) 11, and an SpO for acquiring the patient's plethysmographic signal (PAP) 12. 2 A sensor 4 , the signal corresponding to the pulsation of the patient's blood at said sensor measurement point, and an ECG sensor 5 for measuring the ECG signal 13 . All signals, the PAP signal 11, the plethysmographic signal 12, and the ECG signal 13 include respirat...

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...
