title: Laser Doppler flowmetry and transcutaneously measured carbon dioxide tension for observing changes of skin blood flow in fingers.
abstract: Laser Doppler flowmetry (LDF) and transcutaneous carbon dioxide tension measurements (PtcCO2) were performed on fingers of healthy volunteers subjected to a sequence of hydrostatic and thermal stimuli. LDF response using an unheated probe agreed well with measurements made with Xenon133 clearance and strain gauge plethysmography in a previous work. The PtcCO2 results, however, were found not in any way to reflect changes in skin blood flow.
