Tidal volume (TV) challenge improves the reliability of pulse pressure variation (PPV) in predicting fluid responsiveness. Our study evaluated whether carotid peak velocity (CPV) performs similarly.
In haemodynamically unstable patients, changes in CPV and PPV during a TV challenge (6 to 8 ml/kg) were assessed and compared with cardiac output response after fluid bolus.
Key Finding:
Changes in CPV variation predicted volume responsiveness similarly to changes in PPV following a tidal volume challenge.
This suggests CPV may serve as a useful non-invasive alternative for assessing fluid responsiveness in critically ill patients.
