Injury management commonly includes decreasing arterial blood flow to the affected site in an attempt to reduce microvascular blood flow and edema and limit the induction of inflammation. Applied separately, ice and menthol gel decrease arterial blood flow, but the combined effects of ice and menthol gel on arterial blood flow are unknown.

Blood pressure may be measured in capillaries and veins, as well as the vessels of the 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.

The peripheral circulation is extremely important for transporting blood around the body, exchange of nutrients with tissues and storing blood. As the tissues in the body vary their need for blood e.g. during exercise, the peripheral circulation will match the flow to the demand In this article, we will look at how flow is regulated through the peripheral circulation.

This consists of a rubber cuff and a gauge or column of mercury for measuring pressure. The rubber cuff is wrapped about the patient's arm, and then air is pumped into the cuff by means of a rubber bulb. As the pressure inside the rubber cuff increases, the flow of blood through the artery is momentarily checked.

Pulse, the expansion and recoiling of an artery, reflects the heartbeat. The variables affecting blood flow and blood pressure in the systemic circulation are cardiac output, compliance, blood volume, blood viscosity, and the length and diameter of the blood vessels.

Peripheral blood flow refers to blood flow that occurs in the extremities as opposed to blood that flows to the brain, heart, lungs, and vital organs.

Peripheral resistance is the resistance of the arteries to blood flow. As the arteries constrict, the resistance increases and as they dilate, resistance decreases. Blood pressure Blood pressure (BP) is a measure of the force being exerted on the ...

Here are the main points: If peripheral resistance increases, blood flow decreases. The diameter of the blood vessel is inversely proportional to the amount of resistance. If a blood vessel gets clogged, that increases resistance. Vasoconstriction increases peripheral resistance. Vasodilation ...

The usual pressure difference between the left and right ventricles is about 100 mmHg. The normal cardiac output (the blood flow in the above equation) is about 5 liters/minute . The total peripheral resistance is about 20 (mmHg*min/liters).
