blood loss estimation

Blood loss estimation involves assessing the amount of blood a person has lost during an injury or surgery. Healthcare providers often approximate this by looking at visible bleeding, such as blood in dressings, on the floor, or in medical fluids like suction canisters. They may also consider changes in vital signs, like blood pressure and heart rate, to gauge internal blood loss. Accurate estimation helps determine the severity of bleeding and guides treatment decisions, such as fluid replacement or urgent intervention to prevent shock or other complications.
