Dogs increasing their stroke volume by ≥15% in response to fluid administration at each target CVP stage were considered to be responders, and others were defined as non-responders. MABP: mean arterial blood pressure, RAP: right atrial pressure, PAP: pulmonary artery pressure, PCWP: pulmonary capillary wedge pressure, SV: stroke volume, SVV: stroke volume variation, PPV: pulse pressure variation. a) significantlly statistical difference (P<0.05) compaered with the hemodynamic measurement recorded before attained the CVP.
