ABSTRACT:
An automatic skin perfusion measuring system including instrumentation that automatically analyzes perfusion measurements to identify motion artifact and SPP values and a sensor placement device is provided. The instrumentation is configured to ignore motion artifact. Perfusion measurements are designated as SPP values if various criteria are met. SPP value criteria pertain to factors including cuff pressure, perfusion, perfusion change percentages relative to previous and subsequent perfusion measurements, and whether perfusion measurements are increasing or decreasing relative to previous and subsequent perfusion measurements. The sensor placement device assures reliable data is produced when multiple measurements are desired.
