Systems and methods for intelligent medical vigilance with alert cause indication
First Claim
1. A method for monitoring physiology of a person, comprising:
- placing adjacent the person a plurality of sensors configured to detect physiological parameters of the person;
detecting one or more physiological parameters of the person with said sensors;
converting the detected physiological parameters into signals;
analyzing the signals to determine if they satisfy at least one alert condition;
activating an alert when at least one alert condition is satisfied;
generating an alert message on a display to provide an indication of a cause of the alert;
maintaining the alert message on the display until the display is cleared by a user;
analyzing the signals to determine if they satisfy at least one unable-to-measure condition which indicates that at least some of the signals may be unreliable; and
providing an unable-to-measure alert when at least one of the unable-to-measure conditions is satisfied.

Abstract
An intelligent medical vigilance system that observes and analyzes, and, only in the event of a clinically significant negative condition, notifies and reports the event to the care staff utilizing the hospital'"'"'s existing nurse call system. The device includes a bedside unit connected to a pad or coverlet with a sensor array (placed under the patient) and also to an existing hospital nurse call system via an interface. The bedside unit is a wall-mounted unit with a display that becomes active when an alarm condition is enabled. Vigilance alarms are suspended if a patient is detected out of bed. An unable-to-measure alert is provided if the system is unable to reliably monitor. An alert message is generated and maintained on the display screen to inform a responding caregiver of the time and reason for any alarm.

2. A method for monitoring physiology of a person, comprising:
-
placing adjacent the person a plurality of sensors configured to detect physiological parameters of the person; detecting one or more physiological parameters of the person with said sensors; converting the detected physiological parameters into signals; analyzing the signals to determine if they satisfy at least one alert condition; activating an alert when at least one alert condition is satisfied; generating an alert message on a display to provide an indication of a cause of the alert; maintaining the alert message on the display until the display is cleared by a user; placing a second plurality of sensors on a bed to determine the presence thereon or absence therefrom of the person; detecting one or more signals from said second plurality of sensors; analyzing the signals from the second plurality of sensors to determine whether the person is in bed, out of bed, or attempting to exit the bed; and activating a bed exit alarm when the signals from the second plurality of sensors indicate that the person is out of bed or is attempting to exit the bed. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. Apparatus for monitoring physiology of a person, comprising:
-
one or more physiological sensors configured to detect physiological parameters of a person and generate corresponding electrical signals; a processor configured to analyze the signals from the sensors to determine if the signals satisfy at least one alert condition; an alarm system in communication with the processor for activating an alert when at least one alert condition is satisfied; a display in communication with the processor; the processor being configured to generate an alert message on the display to provide an indication of a cause of the alert and to maintain the alert message on the display until the display is cleared by a user; one or more bed exit sensors adapted to be disposed on a bed to determine whether the person is in bed, out of bed, or attempting to exit the bed and to generate corresponding electrical signals; the processor being configured to analyze the signals from the bed exit sensors to determine whether the person is in bed, out of bed, or attempting to exit the bed and to generate an alert message on the display when the signals from the bed exit sensors indicate that the person is out of bed or is attempting to exit the bed, said alert message providing an indication of the time of day when the person exited the bed or attempted to exit the bed and being maintained on the display until the display is cleared by the user. - View Dependent Claims (23, 24, 25, 26, 27, 28)

22. Apparatus for monitoring physiology of a person, comprising:
-
one or more physiological sensors configured to detect physiological parameters of a person and generate corresponding electrical signals; a processor configured to analyze the signals from the sensors to determine if the signals satisfy at least one alert condition; an alarm system in communication with the processor for activating an alert when at least one alert condition is satisfied; a display in communication with the processor; the processor being configured to generate an alert message on the display to provide an indication of a cause of the alert and to maintain the alert message on the display until the display is cleared by a user; wherein the processor is housed in a bedside unit connected to the physiological sensors and to an existing alarm system of the user. - View Dependent Claims (29, 30, 31)
