Figure 1From: The estimation of cardiac output by the Nexfin device is of poor reliability for tracking the effects of a fluid challengeBland-Altman plot for the absolute values of mean arterial pressure obtained from the Nexfin device (MAP noninv ) and from the femoral arterial catheter (MAP inv ) considering all the pairs of measurements performed during the study. N = 72; straight line, bias; dashed line, +2D/-2SD limits of agreement.Back to article page
