What is peripheral circulation?

One of the definitions of the word "periphery" is "external boundary" or "border area". Peripheral circulation in terms of laymen refers to blood flow that reaches the upper and lower limbs of the body and the surface of the skin. The upper and lower limbs and the surface of the skin can be considered beyond the boundary or boundary area of ​​the body. Peripheral circulation can also be freely described as a blood flow to the arms, hands, legs, legs and the highest layers of skin where the blood vessels lie - dermis. Although the epidermis is the highest layer of skin, it does not contain blood vessels, so peripheral circulation concerns blood flow to the dermis and limbs. They need that are carried by blood. For example, the presence of a radial pulse or pulse that felt on the wrist confirms that blood flow is in the hands. It is possible to have normal central pulses and one or more weak peripheral pulses if there is a health condition that affects human peripheral circulation. There are even situations in which central circulation is normal at the same time that peripheral circulation on the limbwell or part of the skin is completely missing.

If health care providers, especially emergency doctors (EMT) and rescuers, broken bones in the field, should verify that there is sufficient peripheral circulation. For example, if the patient's foot is broken and palm before the patient arrives at the medical facility, the physician evaluates at least the dorsalis pedis pulse to ensure that the blood flow reaches the legs. He or she would also talk to the rear tibial pulse. This verification of peripheral circulation is performed before and after splinting.

There are cold hands and legs and pale skin between symptoms of bad peripheral circulation. However, any problems with the circulatory system could cause the same symptoms and other symptoms. Circulation includes not only a pumping effect of the heart, but also the blood flow through a huge network of blood vessels. These blood vessels are arteries that branch into arteriols and finally to the smallest blood vessels, capillariesher beds. They also include veins that branch into venules and finally into a capillary bed.
