Slagæðablæðing

Slagæðablæðing refers to bleeding from an artery. Arteries are blood vessels that carry oxygenated blood away from the heart to the rest of the body. Unlike veins which carry deoxygenated blood back to the heart, arterial blood is under high pressure. This means that bleeding from an artery can be rapid and severe, often appearing as bright red blood that pulses or spurts with each heartbeat.

The causes of arterial bleeding can include trauma such as cuts, stab wounds, or blunt force injuries that sever or damage an artery. Medical conditions like aneurysms, which are bulges in artery walls, can also rupture and cause significant bleeding. Certain medical procedures, such as surgery or interventions involving blood vessels, carry a risk of arterial injury.

The immediate signs of significant arterial bleeding include profuse blood loss, a drop in blood pressure, rapid heart rate, and pale, clammy skin. In severe cases, it can lead to shock and be life-threatening if not addressed promptly. Treatment focuses on stopping the bleeding, which may involve direct pressure, surgical repair of the artery, or interventional radiology techniques. First aid for arterial bleeding involves applying firm, direct pressure to the wound, elevating the injured limb if possible, and seeking immediate medical attention.
