Skin perfusion pressure \u2014 SPP<\/h1>\n\n\n\n

SPP is a noninvasive method that leverages laser Doppler to measure blood perfusion in the microcirculation. It is primarily used in clinical (and clinical research) settings to assess wound healing potential \u2014 especially in patients with chronic conditions such as diabetic foot [1]<\/sup><\/a>.<\/p>\n\n\n\n

One of the main advantages of SPP is that it is not affected by vascular calcification or anatomical structure. When clinical conditions \u2014 such as wounds on the sole or amputated toes \u2014 preclude the application of toe pressure or TcpO2, SPP is a viable alternative.<\/p>\n\n\n

SPP can be measured at multiple sites: on the foot (plantar, dorsal, and toes), on the ankle, and above and below the knee. Blood flow is occluded by placing a pressure cuff over the probe and inflating it above the patient\u2019s resting systolic pressure. The cuff is then gradually deflated until microcirculatory flow returns \u2014 this is the SPP value and is measured in millimeters of mercury (mmHg).<\/p>\n\n\n\n

SPP can help identify ischemic areas (by, for example, using the angiosome concept). Comparing SPP measurements in areas adjacent to a non-healing ulcer can reveal microcirculatory vascular deficiencies.<\/p>\n\n\n <\/div>\n <\/section>\n\n\n
