Abstract:
1. A method for improving reliability of a system for monitoring the physiology of a person, comprising: placing a first plurality of sensors on a bed configured to detect physiological parameters of the person; detecting one or more physiological parameters of the person with said first plurality of sensors; converting the detected parameters to signals; assigning one or more alarm conditions; analyzing the signals to determine if they satisfy at least one of the alarm conditions; activating an alarm when at least one of the signals satisfies an alarm condition; placing a second plurality of sensors on the bed to detect the presence thereon or absence therefrom of the person; detecting one or more signals from said second plurality of sensors; analyzing the signals from said second plurality of sensors to determine whether the person is in bed, out of bed, or attempting to exit the bed; and preventing any new alarm from being activated when the signals from the second plurality of sensors indicate that the person is out of bed or is attempting to exit the bed, but continuing any alarm which is active before the sensors detect that the person is out of bed or is attempting to exit the bed.
