A device and a process for determining the change in the functional residual capacity (FRC) in a simple manner. Based on a first respiration phase for mechanical respiration, a recruitment maneuver is performed for this during a second respiration phase, and respiration is switched back to mechanical respiration during a third respiration phase. Reference values U<SUB>ref/1</SUB>, U<SUB>ref/3 </SUB>are formed from the end-expiratory values of the impedance measured signals U during the first respiration phase and the third respiration phase, and the difference DeltaU (DeltaFRC) between the reference value U<SUB>ref/3 </SUB>of the third respiration phase and the reference value U<SUB>ref/1 </SUB>of the first respiration phase is an indicator of the change in the functional residual capacity of the lung of the test subject.
