Assessing fluid responsiveness in critically ill patients: false-positive pulse pressure variation is detected by Doppler echocardiographic evaluation of the right ventricle

Objectives: To determine whether peak systolic velocity of tricuspid annular motion
assessed by tissue Doppler echocardiography (Sta), a right ventricular function parameter,
can discriminate patients with true-and false-positive pulse pressure variation. Pulse
pressure variation is used to predict fluid responsiveness in mechanically ventilated
patients. However, this parameter has been reported to be falsely positive, especially in
patients with right ventricular dysfunction. Design: A prospective study. Setting: Medical and …
