Exsanguination
process of blood loss, to a degree sufficient to cause death / From Wikipedia, the free encyclopedia
Exsanguination is losing enough blood to cause death. A person does not have to lose all of their blood to exsanguinate. People can die from losing half to two-thirds of their blood.[1]
The average adult has about 4 to 6 liters of blood (9 to 12 US pints) in their body. The average man has more blood than the average woman (who has 4 to 5 liters), and people who weigh more or are taller than others have more blood.[1] This means a person can die from losing 2 1/2 to 4 liters of blood. To compare, this is five to eight times as much blood as people usually give in a blood donation.[2]
Babies (have about one cup of blood) and children have much less blood than adults, and can exsanguinate much easier by losing less blood than adults.[3] The liver can and does store up to one pint of blood.
Exsanguination is often called bleeding to death or bleeding out. It is a medical emergency.
