Changes in hemodynamic variables pre and post blood donation in orthostatic tolerant donors (OT) and orthostatic intolerant donors with severe symptoms (OI-SEV) and without severe symptoms (OI-NONSEV) during a standardized mobilization procedure. All data presented as mean ± SEM: *P < 0.05 compared with OT patents after blood donation.

CO = cardiac output; DAP = diastolic arterial pressure; HR = heart rate; MAP = mean arterial pressure; PPI = peripheral perfusion index; SAP = systolic arterial pressure; ScO2 = cerebral tissue oxygenation; SEM = standard error of the mean; SmO2 = muscular tissue oxygenation; SV = stroke volume; SVR = systemic vascular resistance
