    • The invention relates to a device, with which one is to prevent a patient who breathes on Ms own and who desires a lower CO 2 -ρartial-ρressure than is achieved by the set Ventilation from tiring. It comprises the following means for the regulation of a changing intensity of a mechanical Ventilation: • means for determining a target frequency RR sp , • means for determining a spontaneous frequency RR spont • means for comparing the spontaneous frequency RR spont with the target frequency RR sp . wherein adapting a Ventilation target value (%MinVol, V´ gA sp ) on account of the result of the comparison of the spontaneous frequency RR spont with the target frequency RR sp and • means for adapting the parameters determining the intensity of the Ventilation, on account of the Ventilation target value (%MinVol, V' gA sp ). This so-called pump support System (PSS)is activated (PSS on) when the patient breathes in an adequately spontaneous manner (Criterion 1). With an insufficient individual activity of the patient, his behaviour is taken as a basis for the control of the regulation. The control or regulation of the Ventilation is assumed by a fixed setting of a Ventilation target value (%MinVol), or a CO 2 -controller, as soon as the patient breathes in a manner which is not spontaneous enough.
