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 statistically significance 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.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
