Fig. 3From: Serial assessments of cardiac output and mixed venous oxygen saturation in comatose patients after out-of-hospital cardiac arrestCorrelation between first measured mixed venous saturation and first measured cardiac index in all patients with regression line (solid line), 95% confidence limits (filled color area) and 95% prediction limits (thin solid line). Dots change color within the filled color area to improve contrast. Vertical line indicates cardiac index at the median value, and horizontal line indicates mixed venous oxygen saturation (SVO2) at the median valueBack to article page
