Hemodynamic monitoring gives early warning of changes in a critically ill patient's condition. Accuracy is essential; for example, a blood pressure cuff is inaccurate at low pressures. Hospitalized adults will usually have a higher central venous pressure, so a CVP less than 4 cm H(2)O may indicate hypovolemia. ⋯ Measurement of cardiac output eliminates the need for arterial and mixed venous blood samples, and can be valuable in decision-making. Calculation of vascular resistance can also be very important in management of the critically ill. With today's facilities, routine clinical assessment is no longer adequate care for these patients.
