Abstract

A monitoring device operable to provide information on data obtained from sensors operably connected between a patient and the device is provided that includes a central processing unit configured to receive incoming data signals from sensors concerning physiological parameters of the patient to compare the incoming data signals to predetermined alarm limits for the physiological parameters to determine an alarm condition and an analytics engine operably connected to the central processing unit and selectively operable to provide predictions of adverse events using the incoming data signals. The central processing unit is configured to alter the alarm limits for at least one of the physiological parameters in response to the activation of the analytics engine to reduce clinically irrelevant alarms.

Claims

1. A method for optimizing alarm settings, the method comprising:

receiving incoming data signals from a first sensor concerning a first physiological parameter and from a second sensor concerning a second physiological parameter of a patient;

determining whether an analytics engine is activated, wherein the analytics engine, when activated, predicts adverse events for the patient using the incoming data signals concerning the first physiological parameter and the second physiological parameter;

in response to determining that the analytics engine is not activated, applying a first alarm setting to the incoming data signals for triggering alarms;

in response to determining that the analytics engine is activated, applying a second alarm setting to the incoming data signals for triggering alarms, wherein the second alarm setting is different from the first alarm setting; and

wherein applying the first alarm setting comprises;

comparing the incoming data signals concerning the first physiological parameter to an alarm limit for the first physiological parameter;

comparing the incoming data signals concerning the second physiological parameter to an alarm limit for the second physiological parameter; and

triggering an alarm if either the alarm limit for the first physiological parameter or the alarm limit for the second physiological parameter is exceeded;

applying the second alarm setting comprises;

comparing the incoming data signals concerning the first physiological parameter to an alarm limit for the first physiological parameter;

comparing the incoming data signals concerning the second physiological parameter to an alarm limit for the second physiological parameter; and
