Abstract
A capnotracking method for continuous determination of cardiac output or EPBF of a mechanically ventilated subject includes the steps of measuring expiratory CO2 of the subject and determining a first value of cardiac output or EPBF of the subject at a first point in time; controlling the mechanical ventilation of the subject to keep a level of venous CO2 of the subject substantially constant between the first point in time and a second point in time; determining from the expiratory CO2 measurements a change in alveolar CO2 of the subject between the first and second points in time; and determining a second and updated value of cardiac output or EPBF of the subject based on the first value and the change in alveolar CO2.
