Slagæðablóði

Slagæðablóði is a term that refers to arterial blood, which is the blood that flows through the arteries of the circulatory system. Arteries carry oxygenated blood away from the heart to the rest of the body, with the exception of the pulmonary artery, which carries deoxygenated blood from the heart to the lungs. Slagæðablóði is typically bright red in color due to its high oxygen content and is under higher pressure than venous blood.

The measurement of slagæðablóði, or arterial blood pressure, is a vital sign used to assess cardiovascular health. It reflects the force exerted by circulating blood against the walls of arteries. This pressure is determined by the amount of blood the heart pumps and the resistance of the arteries to blood flow. High blood pressure, or hypertension, can increase the risk of heart disease, stroke, and kidney problems. Conversely, low blood pressure, or hypotension, can lead to dizziness, fainting, and in severe cases, shock.

Arterial blood gas (ABG) analysis is a medical test that measures the levels of oxygen and carbon dioxide in the slagæðablóði, as well as the blood's pH. This test provides crucial information about a patient's respiratory and metabolic status, helping healthcare professionals diagnose and manage conditions affecting the lungs, kidneys, and metabolism. Sampling slagæðablóði is typically performed by a trained medical professional due to the higher pressure within the arteries.
