Summary: | A method for determining the functional residual capacity of a patient's lung, includes supplying a first inspiratory breathing gas having a first proportion of a metabolically inert gas, supplying a second inspiratory breathing gas having a second proportion of the metabolically inert gas, determining any arising volume difference, which represents a difference in volume between a volume of inspiratory and of expiratory metabolically inert gas for a determination period, determining the functional residual capacity taking into account the volume difference and a proportion difference between a first proportion quantity and a second proportion quantity, which represent the first proportion and the second proportion of the metabolically inert gas, respectively, and determining a base difference, which represents a difference between a tidal volume of inspiratory metabolically inert gas and of expiratory metabolically inert gas. |
