Haemodynamic monitoring facilitates effective resuscitation and the rapid assessment of the response to time-dependent vasoactive and fluid therapyin different shock states. Since the introduction of the pulmonary artery catheter, several minimally and non-invasive CO monitoring devices have been introduced to provide continuous monitoring and a dynamic profile of fluid responsiveness. Several of these monitors provide additional haemodynamic parameters including dynamic indices of preload and volumetric indices. Patient outcome is dependent accurate acquisition and interpretation of data and subsequent management. Whilst data from CO monitors offer valuable information on global hamodynamics, they do not preclude tissue hypoperfusion. Furthermore, there is no ‘ideal’ CO value for an individual patient, and the trend in haemodynamic parameters in response to therapy may be more informative than the absolute values. CO monitoring should be based upon the patient’s needs, the clinical scenario, and the experience of the treating physician.
