Non-Invasive Estimation of the Effective Pulmonary Blood Flow and Gas Exchange from Respiratory Analysis

  • P. Christensen
Part of the Update in Intensive Care and Emergency Medicine book series (UICM, volume 28)


Monitoring of the effective pulmonary blood flow is important in the control of many intensive care therapies such as effect of drugs, optimization of PEEP level and ventilatory settings. A large number of methods have been developed for estimation of the effective pulmonary blood flow. However, only the indicator dilution combined with estimation of the pulmonary shunt have gained widespread use for clinical purposes. The drawback of the indicator dilution method is that it is an invasive method which require access to the pulmonary artery as well as a systemic artery. The increasing demands for noninvasive methods have led to the development of a number indirect methods of which the inert gas rebreathing method have gained most acceptance.
