Systems and methods for monitoring physiology with unable-to-measure alerts
First Claim
1. A method for improving the reliability of a system 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 parameters to signals;
assigning one or more alert conditions;
analyzing the signals to determine if they satisfy at least one of the alert conditions;
activating an alert when at least one of the signals satisfies an alert condition;
assigning one or more unable-to-measure conditions which indicate that at least some of the signals are unreliable;
analyzing the signals to determine if they satisfy at least one of the unable-to-measure conditions; and
providing an unable-to-measure alert when at least one of the unable-to-measure conditions is satisfied.

Abstract
A system that observes and analyzes, and, only in the event of a significant negative condition, notifies and reports the event. In a hospital environment, 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. The system also may be adapted for use as a monitoring system for operators of motor vehicles, aircraft or other devices.

13. 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 physiological parameters of the person satisfy at least one alert condition; and an alert system in communication with the processor for providing an alert when at least one of the physiological parameters satisfies an alert condition; the alert system being further configured to provide an unable-to-measure alert when the processor determines that the signals satisfy an unable-to-measure condition which indicates that at least some of the signals are unreliable. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
