Systems and methods for non-invasive monitoring of vital signs of a subject use multiple coupling sensors and vital sign sensors in order to determine multiple vital sign states of the subject. The sensors may be carried by support structure such as a wrap, blanket, mattress, cradle, nest and similar structures. Signals generated by the coupling sensors reflect coupling strength and/or reliability between sensors and the patient. Coupling reliability indexes may be determined for each of the temperature sensors and displayed to a user. Positional information/mapping of temperature information can be derived from the coupling sensors, image sensors, and/or the variation of the temperature profile itself over time. The measurements may be used to construct a full-body profile of the subject and provide targeted control of devices that affect vital sign states, such as heating/cooling. |
