Abstract

Clinical monitoring of shock mainly depends on blood-oxygenindices obtained from invasive blood sample tests. The central internal jugular central vein oxygenation level (ScvO₂) has been considered as a gold standard indicator for shock prediction. We developed a noninvasive spatially-resolved near-infrared spectroscopy (SR-NIRS) to measure tissue blood oxygen saturation (StO₂) surrounding the region of taking blood sample for the ScvO₂ test in 25 patients with shock. StO₂ values were found to be highly correlated (r = 0.84, p < 0.001) with ScvO₂ levels and the concordance coefficient of 0.80 is high. The results suggest the potential of noninvasive SR-NIRS for bedside shock monitoring.
