WebAbstract —Ratio of stroke volume (SV, M-mode echocardiography) to pulse pressure (PP) has been proposed as an estimate of total arterial compliance and has been shown to be related to body size, age, and heart rate in normal adults. WebSystemic and pulmonary vascular resistance (SVR and PVR), cardiac index (CI), and stroke volume index (SVI) were calculated from measured variables using standard equations. The anesthetic regimen for both the non-CPB and CPB periods was standardized to a combination of sufentanil, midazolam, and isoflurane as needed. The stroke volume (SV), cardiac output (CO), and systemic vascular resistance (SVR) are all derived from two ultrasound measurements: the left ventricular outflow tract diameter (LVOTD) and the left ventricular outflow tract velocity time integral (LVOT VTI) .
