Right ventricular end-diastolic volume index as a predictor of preload status in patients on positive end-expiratory pressure

Abstract

CI correlates significantly better with RVEDVI than PAOP at all levels of PEEP up to 50 cm H2O. RVEDVI is a more reliable predictor of volume depletion and preload recruitable increases in CI, especially in patients receiving higher levels of PEEP where PAOP is difficult to interpret.
