Summary We evaluated the utility of noninvasive stroke volume variation ( SVV ) as a functional haemodynamic predictor for fluid responsiveness under different ventilation modes (assist control [A/C], synchronized intermittent mandatory ventilation [ SIMV ], and continuous positive airway pressure [ CPAP ]) in 45 anaesthetized dogs, using an electrical velocimetry device. Receiver operating curve analysis confirmed the best predictive value during SVV A /C (12.5% of cut‐off value; 75% sensitivity and 86% specificity) followed by SVV SIMV (13.5% of cut‐off value; 75% sensitivity and 75% specificity), while no statistical significance was detected during SVV CPAP ( P > .05). These data suggest that SVV is useful for the prediction of fluid responsiveness in laboratory dogs during A/C and SIMV , while its reliability during CPAP is poor.
