A semiquantitative determination of the cutaneous blood flow is possible by a simple thermic method using a heat conduction probe. There is a quantitative uncertainty because of the possible existence of relatively big vessels which do not participate in the blood supply of the examined tissular region but in the determination of the convection within the temperature field of the thermal conduction probe. The values of blood circulation derived from the stationary temperature field will therefore always be higher than the values of the real blood supply. This procedure necessitates a determination of the tissular heat conductivity. This will not be possible in all cutaneous regions. A relative method can be useful here inserting a binding lambda G value which lies below the thermal transport value lambda for normal blood circulation.
使用热传导探头的简单热学方法可对皮肤血流进行半定量测定。由于可能存在相对较大的血管，它们不参与被检查组织区域的血液供应，但却参与热传导探头温度场内对流的测定，因此存在定量不确定性。由稳定温度场得出的血液循环值将始终高于实际血液供应值。此过程需要测定组织的热导率。这并非在所有皮肤区域都可行。在此插入一个低于正常血液循环热传递值λ的结合λG值的相对方法可能会有用。
