Calculation Formula

SVR = 80*(Mean Arterial Pressure - Central Venous Pressure) / Cardiac Output

Explanation

English Name: Systemic Vascular Resistance, SVR

Normal Range: 800～1200 dynes*s/cm5

Resistance to blood flow in the systemic circulation. It is derived from the frictional resistance between the blood and the vessel walls and the internal friction within the blood. It is related to blood viscosity, vessel length, elasticity, and vessel radius.
