Because of the high pressure and therefore rapid loss of blood,
Arterial bleeding is the most severe and urgent type of bleeding. It can result from a penetrating injury, blunt trauma, or damage to organs or blood vessels. Because the blood comes from the arteries, it is distinctive from the other types of bleeding. For example, the blood is bright red due to it containing oxygen.
Capillary bleeding
You may see a fast flow of blood at first, but it usually slows to a trickle and is easily managed. Often, capillary bleeding will stop on its own. If needed, applying a Band-Aid or other bandage can help stop it—just be careful not to get the sticky part of the Band-Aid on the cut.
Capillary bleeding occurs in all wounds. It is the least serious of the 3 types of bleeding, since it is the easiest to control and results in the least blood loss. Blood 'trickles' out of capillaries for a short while before the bleeding stops.
There are 3 main types: arterial bleeding, venous bleeding, and capillary bleeding.
Capillary bleeding is a much more common form resulting from injury to the integumentary system. Capillary bleeding is characterized by oozing blood from the damaged area. Capillary bleeding can be the most painful but the easiest to control due to its superficial nature.
'Critical bleeding' may be defined as major haemorrhage that is life threatening and likely to result in the need for massive transfusion.
RE-LY definition of life-threatening bleeding: ≥ 1 of the following criteria: (1) fatal, symptomatic intracranial bleed; (2) reduction in hemoglobin level of at least 5.0 g/L; (3) transfusion of at least 4 U of blood or packed cells; (4) associated with hypotension requiring the use of intravenous inotropic agents; or ...
Bleeding disorders such as hemophilia and von Willebrand disease result when the blood lacks certain clotting factors. These diseases are almost always inherited, although in rare cases they can develop later in life if the body forms antibodies that fight against the blood's natural clotting factors.
Venous bleeding distinctions are: The blood is dark red, not bright like arterial bleeding. The blood flow is steady but not spurting; it can still be quick, though. The pressure is lower than arterial bleeding so it's usually easier to control.
With venous bleeding, the blood runs out from the wound site at a steady rate. The color of the blood with venous bleeding is dark red to purplish in color. With arterial bleeding, the blood comes from the artery and pumps out with each heartbeat. The blood can also spurt out with arterial bleeding.
Put pressure directly on an external wound with a sterile bandage, clean cloth, or even a piece of clothing. If nothing else is available, use your hand. Direct pressure is best for external bleeding, except for an eye injury. Maintain pressure until the bleeding stops.
If you need to change your tampon or pad after less than 2 hours or you pass clots the size of a quarter or larger, that is heavy bleeding.
Hitting an artery can be painful and dangerous. Arterial blood travels away from the heart so whatever is injected goes straight to body limbs and extremities. Injection particles get stuck in blood capillaries and cut off circulation. This can result in a lack of blood flow, eventually causing the tissue to die.
Fatal bleeding (bleeding that directly results in death)
Injuries, such as cuts or puncture wounds, bone fracture or traumatic brain injury. Violence, such as a gunshot or knife wound, or physical abuse. Viruses that attack the blood vessels, such as viral hemorrhagic fever.
There are about 2,000 mL or 0.53 gallons of blood in the average adult. And losing more than 800 mL of blood is fatal. According to WHO, an estimated 5million people lost their lives due to this, roughly about 9% of the global annual mortality rate.
It is typically estimated as where the adult casualty has lost c. 250mls or 1/2 pint of blood.
CAPILLARY – Small cuts and scrapes open the capillaries, and bleeding occurs. The bleeding is slow and generally clots within a matter of minutes.
To stop bleeding, first try applying direct pressure. Once the bleeding stops, tie a cloth, gauze or towel tightly around the wound without cutting off circulation.
