![]() The key difference involves the area of the body affected. When this happens, the body body diverts blood from the skin toward the internal organs. If a clot forms in a vein in the leg, for example, peripheral cyanosis may develop in that limb. This can prevent the heart from pumping blood around the body effectively. If a health condition affects an artery that delivers blood and oxygen to the hands and feet, peripheral cyanosis may result. This involves the body’s temperature dropping dangerously low. Low blood pressure can keep enough blood and oxygen from reaching the hands and feet. The blood vessels narrow, preventing blood from reaching the extremities. This causes the fingertips and toes become numb, as well as bluish or whitish, in cold temperatures. People tend to experience cyanosis in the extremities, such as the fingertips and feet, because these areas are farthest from the heart, so the blood has longer to travel.Ĭommon causes of peripheral cyanosis include: Some people are born with hemoglobin that has a limited ability to bind to oxygen and carry it to the cells. It also looks at another type called central cyanosis, which affects core organs in the body, as well as the lips, tongue, or both.Ĭertain medical conditions can prevent oxygen-rich blood from reaching parts of the body. This article takes a close look at peripheral cyanosis, including its causes, symptoms, and treatment. A person should seek medical attention if they develop the symptoms. Cold temperatures, circulation problems, and tight jewelry are common causes. “Peripheral” cyanosis affects the extremities. The primary symptom is blue discoloration of the skin. The condition gets its name from the word “cyan,” a blue-green color. If the blood cannot deliver enough oxygen to an area of the body, cyanosis may occur. Blood contains a protein called hemoglobin that carries oxygen to the body’s cells. A person’s body absorbs oxygen from the air that they breathe. Possible causes include Raynaud’s disease, cardiovascular problems and hypothermia.Īll organs and tissues need oxygen to function. Peripheral cyanosis is when the hands, fingertips, or feet turn blue because they are not getting enough oxygen-rich blood.
