Abstract

The purpose of this study is to examine the influence of the skin perfusion pressure of lower limbs by the difference of the leg position, and to use it in a clinical practice. The subjects were assumed to be ten healthy, young adults (4 males and 6 females). The skin perfusion pressure of lower limbs was measured in four positions (supine, lower limbs elevation, bed elevation 20°, and sitting position). The measurements were taken in two places, the dorsum of foot and the plantar of foot right lower extremity. Moreover, the systolic blood pressure, the diastolic blood pressure, and the pulse rate of right lower extremity were measured. The skin perfusion pressure of the lower limbs rose significantly compared with the supine and the lower limbs elevation when the lower limbs were lowered from the cardiac position (p<0.01, p<0.05). A positive correlation was shown between skin perfusion pressure and the systolic blood pressure. As for the bed elevation 20°, the lower limbs skin perfusion pressure rose significantly more than the supine and the lower limbs elevation.
