Why the study?
Does RVEDV measured by a residual fraction Swan-Ganz catheter accurately predict LVEDV measured by transesophageal echocardiography in critically ill patients?

RVEDV should not guide absolute preload targets in critical illness; leaves open whether serial changes track LVEDV response.
Does RVEDV measured by a residual fraction Swan-Ganz catheter accurately predict LVEDV measured by transesophageal echocardiography in critically ill patients?
RVEDV measured by a residual fraction Swan-Ganz catheter markedly overestimates left ventricular preload compared to transesophageal echocardiography, which could lead to underresuscitation if used as an absolute target.
