Abstract

See full text

A method for the objective determination of capillary refill behavior on a human body surface in which a spatially and spectrally resolved optical detection is carried out by at least one detector device (1) at a skin surface area (2) having a predefined areal size and outer contour. Subsequently a predefined pressure p constant over the skin surface area (2) is exerted over a predefined time t1; and the pressure effect is ended after expiry of this time t1. The spatially and spectrally resolved optical detection is carried out by the detector device (1) and the respective capillary refill behavior is spatially and temporally determined at a time t2 up to which at least one first threshold value of the measurement values detected simultaneously with spatial resolution has reached the measurement value that had been optically detected before the start of the pressure effect.
