Systemic Vascular Resistance

**Semantic type:** Finding

**Definition:** The resistance to blood flow offered by all systemic vasculature, excluding pulmonary vasculature. The major determinant of SVR is arteriolar tone, but blood viscosity and vascular capacitance are also contributing factors.

**Synonyms:** - SVR - Systemic vascular resistance - TPR - Total Peripheral Resistance - Total Peripheral Resistance - Total Peripheral Resistance
