Abstract
The present disclosure relates to a method for determination of cardiac output or EPBF of a mechanically ventilated subject. The method comprises the steps of introducing a change in the effective ventilation of the subject, measuring expiratory flow and CO2 during a sequence of analyzed breaths during which the effective ventilation of the subject varies, and determining the cardiac output or EPBF of the subject using the flow and CO2 measurements. The method further comprises the steps of measuring also a relative variation in cardiac output or EPBF during the sequence of analyzed breaths, and using the relative variation in the determination of cardiac output or EPBF.
