WebSVR can be calculated if cardiac output (CO), mean arterial pressure (MAP), and central venous pressure (CVP) are known. SVR = (MAP - CVP) ÷ CO. Because CVP is normally near 0 mmHg, the calculation is sometimes simplified to: SV ≅ MAP ÷ CO. The units for SVR are most commonly expressed as pressure (mmHg) divided by cardiac output … Web12 sep. 2024 · A central venous pressure is the pressure in the thoracic vena cava near the right atrium.
