Abstract
A process and a signal processing unit determine a pneumatic parameter (P) for the spontaneous breathing of a patient. The patient is ventilated mechanically by a ventilator. A lung-mechanical model () and a gradient model () are preset. The lung-mechanical model () describes a relationship between the pneumatic parameter (P) as well as a volume flow signal (Vol′), a volume signal (Vol) and/or a respiratory signal (Sig), which can be measured. The gradient model () describes a value for the pneumatic parameter (P) as a function of N chronologically earlier values of the pneumatic parameter (P) or of a variable correlating with the pneumatic parameter (P). N values for the correlating variable are determined at first. At least one additional value is subsequently determined for the pneumatic parameter (P). N chronologically earlier values of the correlating variable, current signal values, the lung-mechanical model () and the gradient model () are used for this purpose.
