Abstract :
We used an optoacoustic technique to measure continuously and noninvasively total hemoglobin concentration in human blood in vivo. An optoacoustic probe, which combined illuminating fibers and a piezoelectric sensitive element, was placed in contact with the skin over the radial artery. Measurements in healthy volunteers agreed well with actual hemoglobin concentration.
