  1. Baseline measurements and measurements during 0 - 2 min, 2 - 4 min, 4 - 6 min, 6 - 8 min and 8 - 10 min of mechanical chest compressions. AP = intrathoracic aortic pressure, CVP = Central Venous Pressure (right atrial pressure), CPP = calculated coronary perfusion pressure, APV = Average peak velocity. Data are presented as mean ± SD, n = 10.
