Exsanguination is the loss of blood from the circulatory system of a vertebrate, usually leading to death. The word comes from the Latin 'sanguis', meaning blood, [1] and the prefix 'ex-', meaning 'out of'. Exsanguination has long been used as a method of animal slaughter.
Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. [2] 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). [3]
When resulting from blood loss, trauma is the most common root cause, but severe blood loss can also happen in various body systems without clear traumatic injury. [3] The body in hypovolemic shock prioritizes getting oxygen to the brain and heart, which reduces blood flow to nonvital organs and extremities, causing them to grow cold, look ...
The presence of bright red blood in stool, known as hematochezia, typically indicates lower gastrointestinal bleeding. Digested blood from the upper gastrointestinal tract may appear black rather than red, resulting in "coffee ground" vomit or melena. [2] Other signs and symptoms include feeling tired, dizziness, and pale skin color. [18]
The severity of hemorrhagic shock can be graded on a 1–4 scale on the physical signs. The shock index (heart rate divided by systolic blood pressure) is a stronger predictor of the impact of blood loss than heart rate and blood pressure alone. [11] This relationship has not been well established in pregnancy-related bleeding. [12]

The most common cause of death in trauma is bleeding. [6] Death from trauma accounts for 1.5 million of the 1.9 million deaths per year due to bleeding. [4] There are two types of trauma: penetrating trauma and blunt trauma. [2] Penetrating trauma is the most common cause of vascular injury and can result in internal bleeding.
