Nurse-driven glucose control consists of the repetitive execution of the cycle depicted in this figure. First, the nurse acquires blood from the patients and gets the glucose level. A protocol or doctor then decides what action should be taken (in most cases a change of the rate of the insulin pump), and subsequently this action is performed at the bedside by the nurse.Back to article page
