The peripheral factors that determine blood pressure pertain to the blood vessels and blood. It includes peripheral resistance, blood volume, elasticity of blood vessels, velocity of blood flow, venous return, viscosity of blood and diameter of blood vessels.

Five factors influence blood pressure: Cardiac output; Peripheral vascular resistance; Volume of circulating blood; Viscosity of blood; Elasticity of vessels walls . Blood pressure increases with increased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and rigidity of vessel walls.

Normally the viscosity of blood does not change over short periods of time. The two primary determinants of blood viscosity are the formed elements and plasma proteins. Since most formed elements are erythrocytes, any condition affecting erythropoiesis, such as polycythemia or anemia, can alter viscosity. Since most plasma proteins are produced ...

Any factor that causes cardiac output to increase, by elevating heart rate or stroke volume or both, will elevate blood pressure and promote blood flow. These factors include sympathetic stimulation, the catecholamines epinephrine and norepinephrine, thyroid hormones, and increased calcium ion levels.

2023年7月31日 · Explore the various factors that determine blood pressure in humans, including central and peripheral factors. Also, find answers to frequently asked questions about blood pressure determinants.

2019年11月6日 · Determinants of blood pressure: There are multiple factors which influence the blood pressure: Cardiac output Heart rate; Stroke volume; Blood volume; Total peripheral resistance; Viscosity of the blood; The elasticity of vessel walls; The blood pressure increases if any of the first 4 factors increase.

2015年12月6日 · Physical determinants of arterial blood pressure. Where blood pressure is discussed in textbooks, it is usually described in terms of the relationship between flow and resistance, crudely approximated using Ohm's law (Q=∆P/R), which describes the relationships of pressure resistance and flow: Pressure is the product of resistance and flow:

2021年5月23日 · Blood pressure (BP) is the force exerted by the blood against a vessel wall. The mean arterial pressure (MAP) is the average pressure throughout the cardiac cycle (normally about 93 mm Hg).

2018年10月11日 · Blood pressure is one of the most commonly measured clinical parameters and blood pressure values are major determinants of therapeutic decisions. However, interpretation of the physiological meaning of blood pressure in an individual patient is not always an easy task.

Blood pressure may be measured in both the systemic and pulmonary circulation; however, the term blood pressure without any specific descriptors typically refers to systemic arterial blood pressure—that is, the pressure of blood flowing in the arteries of the systemic circulation.
