1. 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 or blood flow, wherein the system comprises:
a wristband device for gathering measurement data of the patient, and a data processing unit for processing said measurement data in order to provide said early risk recognition monitoring, wherein said wristband device and data processing unit are configured to communicated with each other via a two-way data communication link so that said wristband device is configured to send said measurement data to the data processing unit for the monitoring and early risk recognition determination processes,wherein the wristband device comprises:
a first infrared temperature sensor configured to measure first temperature (t1) of the patient at the first wrist point, said first wrist point being at the area of distal antebrachium, and a second infrared temperature sensor configured to measure second temperature (t2) of the patient at the second finger point, said second finger point being a root end of the finger, whereupon the system is configured to determine altered peripheral tissue perfusion by determining temperature gradient (Δt) between said first and second points, and if the determined temperature gradient (Δt) exceeds a predetermined range, the system is configured to construe: an (Δt) exceeding of the upper limit of the range as a peripheral vasoconstriction or an (Δt) deceeding of the lower limit of the range as a peripheral vasodilatation, and thereby configured to provide first early risk recognition phase (p1). |
