When brought to the emergency room, an accident victim has 3 liters of blood and is still losing blood at a rate of 0.25 liters per hour. He is immediately given continuous blood transfusions at 0.5 liters per hour, and an antibiotic drug is administered intravenously at 0.5 grams per hour. Four hours later, the bleeding has stopped but the transfusions continue for an additional two hours.
