Ejection fraction (EF) corrected volumetric parameters better reflect preload and fluid responsiveness

Excerpt

Volumetric monitoring with right ventricular end-diastolic volume indexed (RVEDVi) and global end-diastolic volume indexed (GEDVi) is increasingly being suggested as a better preload indicator than traditional intracardiac filling pressures (central venous pressure [CVP] and pulmonary artery occlusion pressure [PAOP]). Static volumetric monitoring, however, has not consistently been shown to correlate with the cardiac index (CI). This study aims (1) to evaluate the influence of ejection fraction (EF) on RVEDVi and GEDVi, (2) to study the effect of RVEDVi and GEDVi changes (Δ) corrected for right ventricle ejection fraction (RVEF) and global ejection fraction (GEF), respectively, on ΔCI, and (3) to identify optimal resuscitation target volumes. …
