“…Its accuracy in one lung ventilation for thoracic surgery is open to question, because of the substantial changes in ventilation-perfusion relationships in the lung that occur. However, a study by Ng et al using the NICO ® found relatively good preservation of accuracy with the change from two lung to one lung ventilation, with the biggest increase in bias seen early after the change and subsequently reducing [40,79]. Peyton et al have reported that the differential Fick CO 2 method based on the original method of Gedeon et al [29] employed in their studies does not work reliably in that small proportion of patients with severe obstructive lung disease with chronic gas trapping [58].…”

Minimally invasive measurement of cardiac output as a central component of advanced haemodynamic monitoring has been increasingly recognised as a potential means of improving perioperative outcomes in patients undergoing major surgery. Methods based upon pulmonary carbon dioxide elimination are among the oldest techniques in this field, with comparable accuracy and precision to other techniques. Modern adaptations of these techniques suitable for use in the perioperative and critical are environment are based on the differential Fick approach, and include the partial carbon dioxide rebreathing method. The accuracy and precision of this approach to cardiac output measurement has been shown to be similar to other minimally invasive techniques. This paper reviews the underlying principles and evolution of the method, and future directions including recent adaptations designed to deliver continuous breath-by-breath monitoring of cardiac output.
