System and method to detect changes in health parameters and activate lifesaving measures

A system comprising:

• a commonly worn object including one or more biometric sensors configured to detect biometric data of a user, the commonly worn object has situational calibration based on a physically measured value measured during a movement of the user;
• and
• one or more processors in communication with the one or more biometric sensors, wherein the processor is configured to:
• determine whether the user has experienced a physiological and detrimental change by comparing the physically measured value and the biometric data to one or more thresholds;
• and
• generate an alert based at least partly on the determining of whether the user has experienced the physiological and detrimental change.

A wearable wrist device comprising:

• one or more biometric sensors configured to detect biometric data of a user, the one or more biometric sensors situationally calibrated based on a physically measured value measured during a movement of the user;
• and
• a processor in communication with the one or more biometric sensors, the processor configured to:
• determine whether the user has experienced a physiological and detrimental change by comparing the physically measured value and the biometric data to one or more thresholds;
• and
• generate an alert based at least partly on the determining of whether the user has experienced the physiological and detrimental change.

A method comprising:

• detecting, by at least one commonly worn object which is situationally calibrated, a user activity state;
• measuring biometric parameters during the user activity state;
• and
• generating alerts for at least some of the biometric parameters that are outside a range for the user activity state, the range being defined by the commonly worn object being situationally calibrated.
