Fig. 6From: Near-Infrared Spectroscopy measurements are reliable for studying patellar bone hemodynamics and affected by venous occlusion, but not by skin compressionPlotted means of HHb and O2Hb (in µmol/cm.2) of Experiment 1 ‘Venous Occlusion’ and Experiment 2 ‘Skin Compression’. Abbreviations: HHb, deoxygenated hemoglobine; O2Hb, oxygenated hemoglobine for each optode (30, 35, 40 mm); min, minutes; A, baseline (3 min); B, experimental measurement (venous occlusion / skin compression) (1 min); C, recovery time (15 s)Back to article page
