Bleeding

Bleeding, technically known as hemorrhaging or haemorrhaging (see American and British spelling differences), is blood escaping from the circulatory system. Bleeding can occur internally, where blood leaks from blood vessels inside the body, or externally, either through a natural opening such as the mouth, nose, ear, urethra, vagina or anus, or through a break in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery.

Classification

Blood loss

Hemorrhaging is broken down into four classes by the American College of Surgeons' advanced trauma life support (ATLS).

Exsanguination

Exsanguination is the process of blood loss, to a degree sufficient to cause death. One does not have to lose all of one's blood to cause death. Depending upon the age, health, and fitness level of the individual, people can die from losing half or two-thirds of their blood; a loss of roughly one-third of the blood volume is considered very serious. Even a single deep cut can warrant suturing and hospitalization, especially if trauma, a vein or artery, or another comorbidity is involved. It is most commonly known as "bleeding to death" or colloquially as "bleeding out". The word itself originated from Latin: ex ("out of") and sanguis ("blood").

Slaughtering animals

Exsanguination is used as a method of slaughter. Before the fatal incision is made, the animal may be rendered insensible to pain by various methods, including captive bolt, electricity or chemical. Without prior sedation, stunning or anesthetic, this method of slaughter is understood by some to cause a high degree of anxiety, although other studies contradict these findings. The captive bolt is placed against the skull of the animal, and penetrates to cause tissue destruction in the brain, incapacitating the animal so that the procedure may take place. Electricity is used mostly in porcine, poultry and domestic sheep, whereas chemical is used in injured livestock.
