WebCO, CI, SV, SVI and SVV. a WithCVP catheter, its signal may be interfaced with the Vigileo , allowing for the calculation of SVR and SVRI. When used with a central venous oximetry catheter, the Vigileo also provides continuous central venous oxygen satura-tion [15]. The system calculates the arterial pressure using WebSVI (40-50 ml/m2) SV (60-100ml/m2) • Amount of blood ejected with each heartbeat • Use in conjunction with other cardiac pressures to diagnose and evaluate treatment. Contractility Systemic Vascular Resistance (SVR) (800-1400 dynes/sec/cm5) • Resistance that left ventricle must overcome to eject its volume Afterload Waveforms

WebSVI allows a direct comparison between patients with different weights and heights and is used in clinical studies and survival predictions in various cardiovascular diseases. While stroke volume normal values are between 60 and 120 mL, SVI normal range is between 33 and 47 mL/m 2 /beat The average body surface areas are: adult men: 1.9 m 2; WebCO, CI, SV and SVI decreased at the following 20, 40, and 60 minutes respectively.
