Patent ID: 7572230

Claim:
A method for the presentation of information concerning variations of the arterial filling with blood of organs of living beings on a display unit, the method comprising: determining perfusion index data for presentation using an algorithm from measured values produced by a non-invasive photometric measuring process for determining the arterial oxygen saturation of the blood; defining a first perfusion index as a reference value selected from perfusion index values determined during the photometric measuring process; determining subsequent perfusion indices as relative deviations with respect to the reference value; displaying the reference value on the display unit; and presenting said relative deviations as information concerning the variations of the perfusion on the display unit using first and second parallel bar elements for the presentation of the reference value and the relative deviations, respectively, where a length of the first parallel bar element represents the reference value and a variable length of the second parallel bar element represents the relative deviations.
