Basal perfusion of the cutaneous microcirculation: measurements as a function of anatomic position.

摘要: Noninvasive optical techniques of photopulse plethysmography (PPG) and laser Doppler velocimetry (LDV) have been used to identify regional variations in the basal skin blood flow humans. The procedures assess either volume or volume-velocity product cutaneous vessel perfusion. Fifty-two anatomic positions studied 10 normal subjects resting horizontally. mean perfusion levels were ranked reveal as a function body site. Groups data collected into cohorts average values for within each cohort compared by Newman-Keuls multiple comparison test. Most transparently, results collection regions (fingers, palms, face, ears) which is much higher than all other positions. More subtle differences some unexpected similarities, however, are also apparent and, cases, agree or, others, conflict, with previously published information. With exceptions, good general agreement between two was observed.
