Vascular resistance is the resistance that must be overcome for blood to flow through the circulatory system.

2023年7月10日 · Systemic vascular resistance (SVR), also known as total peripheral resistance (TPR), is the amount of force exerted on circulating blood by the vasculature of the body. Three factors determine the force: the length of the blood vessels in the body, the diameter of the vessels, and the viscosity of the blood within them.

Systemic vascular resistance (SVR) refers to the resistance to blood flow offered by all the systemic vasculature, excluding the pulmonary vasculature. This is sometimes referred to as total peripheral resistance (TPR).

2023年5月1日 · Peripheral vascular resistance (systemic vascular resistance, SVR) is the resistance in the circulatory system that is used to create blood pressure, the flow of blood and is also a component of cardiac function. When blood vessels constrict (vasoconstriction) this leads to an increase in SVR.

2023年8月9日 · Explore the physiology of systemic vascular resistance, a key determinant of blood flow regulation and blood pressure maintenance. Learn about its determinants, regulation, and clinical significance in cardiovascular function and diseases.

2023年5月8日 · Peripheral vascular resistance (total peripheral resistance or systemic vascular resistance) refers to the resistance to blood flowing through the arteries and arterioles in the peripheral circulation.

There are three types of vascular resistance: systemic vascular resistance, pulmonary vascular resistance and peripheral pulmonary resistance. It is the resistance that blood “sees” as it travels through the body’s circulatory system.
