The skin perfusion pressure measuring device measures the skin perfusion pressure of the subject to be examined. The measuring apparatus is a measuring instrument for measuring the blood flow of the subject site, a detection part for detecting the height of the subject site, and a change in blood flow of the subject site measured by the measuring instrument in which the height of the subject site is being changed and the detection part Based on the height of the subject to be detected, there is provided a processing section for obtaining the skin perfusion pressure of the subject to be examined.皮膚灌流圧の測定装置は、被検者における被検部位の皮膚灌流圧を測定する。測定装置は、前記被検部位の血流を測定する測定器と、前記被検部位の高さを検出する検出部と、前記被検部位の高さが変更されている状態で前記測定器によって測定された前記被検部位の血流の変化と、前記検出部によって検出された前記被検部位の高さとに基づいて前記被検部位の皮膚灌流圧を求める処理部と、を備える。
