Fig. 7From: Proof of concept non-invasive estimation of peripheral venous oxygen saturationCorrelation (r 2 = 0.95) between all estimated RVen and measured SvO2 samples across the whole cohort from the 3 tests. The solid blue line is the proposed SpvO2 calibration model and the dashed red line is the empirical SpaO2 calibration model related to RArt [25]Back to article page
