The Systemic Vascular Resistance (SVR) is a measure of the resistance to blood flow in the systemic circulation. It reflects the resistance across the whole of the systemic circulation from the aorta to the right atrium and is analogous to left ventricular afterload. The SVR is calculated using the formula SVR = (MAP - CVP) / CO * 80, where MAP is the mean arterial pressure, CVP is the central venous pressure, CO is the cardiac output, and 80 is a conversion factor. A higher SVR indicates greater resistance to blood flow, which can be a sign of certain heart conditions such as hypertension or heart failure.
