Abstract

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 SVVA /C (12.5% of cut-off value; 75% sensitivity and 86% specificity) followed by SVVSIMV (13.5% of cut-off value; 75% sensitivity and 75% specificity), while no statistical significance was detected during SVVCPAP (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.
