Starling curves as a guide to fluid management in the critically ill.

Information derived from Starling curves is useful in following the course of critically ill patients. With this knowledge, the physician can better assess the efficiency of the myocardium and determine the optimal filling pressure. Thus, he is enabled to prescribe the necessary fluid and/or drug therapy to maintain the patient at his most efficient cardiac performance. The nurse who monitors cardiac output and wedge at frequent intervals can regulate fluid replacement on this basis.
