Maull presented several heuristics for estimating blood loss in a patient after severe trauma.
External Blood Loss
Each 1 square foot (929 square cm) of blood (on clothing, on floor) represents approximately 100 mL of blood.
Fractures with Major Blood Loss
Fracture |
Blood Loss |
humerus |
200 - 500 mL |
tibia with/without fibula |
400 - 700 mL |
femur |
1,000 - 1,500 mL |
pelvis |
> 2,000 mL |
ribs |
variable, may be major |
Purpose: To estimate the amount of blood loss associated with severe trauma using the heuristics of Maull.
