External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
The goddess Chinnamastā squirting blood. Blood squirt (blood spurt, blood spray, blood gush, or blood jet) is a projectile expulsion of blood when an artery is ruptured. Blood pressure causes the blood to bleed out at a rapid, intermittent rate in a spray or jet, coinciding with the pulse, rather than the slower, but steady flow of venous bleeding.
Alternatively, arterial occlusion occurs as a consequence of embolism of blood clots originating from the heart ("cardiogenic" emboli). The most common cause is atrial fibrillation, which causes a blood stasis within the atria with easy thrombus formation, but blood clots can develop inside the heart for other reasons too as infective endocarditis.
Numbness and tingling in an arm or leg [1] [2] Paleness [1] [2] of the skin of the arm or leg; Muscle weakness of an arm or leg, [1] [2] possibly to the grade of paralysis [2] Later symptoms are closely related to infarction of the tissue supplied by the occluded artery: Blisters of the skin in the affected area [1] Shedding of skin ...
Arterial thromboembolism (ATE) is a less common but more severe form of thromboembolism, which can affect various organs, such as the brain, heart, kidneys, limbs, and mesentery. ATE can cause life-threatening conditions, such as stroke, myocardial infarction, acute kidney injury, limb ischemia, and mesenteric ischemia.
Arterial embolism can cause occlusion in any part of the body. It is a major cause of infarction (tissue death from blockage of the blood supply). [4] An embolus lodging in the brain from either the heart or a carotid artery will most likely be the cause of a stroke due to ischemia. [5]
Possible complications of arterial embolism depend on the site of the obstruction: In the heart it can cause myocardial infarction [2] In the brain, it can cause a transient ischemic attack (TIA), [2] and, in prolonged blood obstruction, stroke. [2] Blockage of arteries that supply arms or legs may result in necrosis and gangrene [1]
This carries a risk of bleeding and is therefore reserved for those who have a form of thrombosis that may cause major complications. In pulmonary embolism, this applies in situations where heart function is compromised due to lack of blood flow through the lungs ("massive" or "high risk" pulmonary embolism), leading to low blood pressure .
