    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).

    A massive transfusion protocol is used when significant blood loss is present such as in major trauma, when more than ten units of blood are needed. Packed red blood cells, fresh frozen plasma, and platelets are generally administered. [131] Typical ratios of fresh frozen plasma, platelets and packed red blood cells are between 1:1:1 and 1:1:2 ...
