Right ventricular pressure–volume relations and effects of selective vena cava occlusion during cardiopulmonary resuscitation
During CPR, the right ventricular pressure-volume loop transforms into a trapezoidal shape, resembling a left-leaning triangle, because the isovolumetric phases disappear. VCO during CPR reduces ventricular systolic pressures, indicating that a reduction in the venous return affects perfusion pressures during resuscitation.
