摘要
A device for furnishing a breathing gas at alternating pressure levels has a feeder to feed the breathing gas, a pressure adjusting device for triggering the feeder set-point breathing gas pressure signal, furnishes the breathing gas at a set-point, a pressure specification device for generating a pressure signal, and parameter-determination unit for furnishing parameters representative of at least of instantaneous pressure (p), progression of time (t), and instantaneous breathing gas flow (v). The pressure specification device includes a computer circuit configured such that, at least in the expiratory phase, pressure is adjusted on the basis of a dynamic or nonlinear pressure guidance function, which takes parameters into account that are indicative of the breathing gas flow and the progression of time. As a result, the tendency to lowering the breathing gas pressure in conjunction with the extent of the breathing gas flow decreases with increasing progression of time.
