METHOD AND APPARATUS FOR DETECTING A CRITICAL SITUATION OF A SUBJECT
First Claim
1. A process for detecting a critical situation of a subject by measuring a physiological parameter on the subject, the process comprising the following steps:
- (a) measuring the physiological parameter by means of an embedded sensor on the subject;
(b) calculating a variation rate of the physiological parameter;
(c) determining a synthesis variable for the physiological parameter by taking into account at the same time the value of the parameter and its variation rate; and
(d) detecting a critical situation from this synthesis variable.

Abstract
Embodiments of the invention relate to a method for detecting the critical situation of a subject that comprises measuring a physiological parameter of the subject. The method includes (a) measuring the physiological parameter; (b) calculating a variation rate of the physiological parameter; (c) determining a synthesis variable for the physiological parameter by taking into account both the value of the parameter and the variation rate thereof; and (d) detecting a critical situation from the synthesis variable. Steps (a) to (c) may be implemented for at least two physiological parameters, and the method may further include determining a global decision variable from the different synthesis variables, the critical situation being detected during step (d) from the global decision variable. Embodiments of the invention can be used for improving the detection of accidents or health problems, particularly for the elderly at their places of residence.

11. An apparatus for detecting a critical situation of a subject comprising,
at least one embedded sensor capable of measuring a physiological parameter, and a processing unit configured to receive the values measured by the sensor or the sensors and calculating a variation rate of the physiological parameter or of each of the physiological parameters, and determine a synthesis variable for the physiological parameter or each of the physiological parameters by taking into account its value and its variation rate at the same time, for the parameter or for at least one of the parameters.
