1. A method for determining at least one parameter related to the microcirculation function of a person, said method comprising the steps of:
a) determining an arrival time (AT) of a pulse wave, wherein the AT is the time between onset of an activity of a heart that produces said pulse wave and arrival of said pulse wave in a location at a microvasculature in a part of a body of said person;
b) varying an applied pressure (P) on said part of the body over time, wherein the applied pressure (P) compresses at least tissue surrounding the location at the microvasculature in the part of the body, and determining said AT as a function of applied pressure and time; and
c) determining said at least one parameter related to the microcirculation function based on said determination of AT and said AT as a function of applied pressure and time in steps a) and b).
