A system for providing an early risk recognition monitoring by measurement of a peripheral tissue perfusion of a patient instead of clinically significant changes in systemic blood pressure and/or blood flow comprises a wristband device for gathering measurement data of the patient. The device measures a first temperature (t) of the patient at the first wrist (or distal antebrachium) point and a second temperature (t) of the patient at the second finger point, whereupon the system determines altered peripheral tissue perfusion by determining temperature gradient (&#x394;t) between said first and second points. If the gradient (&#x394;t) exceeds or deceeds a predetermined range, the system construes the exceeding as a peripheral vasoconstriction and the deceeding as a peripheral vasodilatation, and thereby provides a first early risk recognition phase (p) and transmits it as a warning indication to end devices of health care personnel.
