The average human body holds about 5 liters of blood. Lose a liter, and you may go into shock. Lose two more, and you’ll probably die.
For doctors treating traumatic injuries, keeping a patient’s blood in their body is “one of the most fundamental problems of survival,” Charles Barber writes in his fast-paced new book, In the Blood.
Solutions to that problem haven’t changed all that much in centuries. Doctors can pack a wound with gauze or put pressure on blood vessels to slow bleeding. While other areas of medicine have leaped ahead over time, Barber notes, emergency medicine has largely stood still, an inertia that’s had deadly consequences. Some 50,000 people in the United States bleed to death every year.
