Fig. 3From: Optimal crystalloid volume ratio for blood replacement for maintaining hemodynamic stability and lung function: an experimental randomized controlled studyMean (±SE) values of hemodynamic parameters during the experimental protocol (both at replacement and withdrawal steps). ΔBV: changes of total blood volume. Absolute values of mean arterial pressure (MAP) and heart rate (HR) over the experimental protocol (left) and their changes following the last replacement compared to baseline (right). BL: baseline. CR1-CR6: replacement maneuvers, W1-W7: blood withdrawal steps. *: p < 0.05 in Group 1 vs BL, #: p < 0.05 in Group 3 vs BL. §: p < 0.05 in the relative changesBack to article page
