Abstract

The invention relates to an artificial lung for simulating the stress by a user when testing a breathing apparatus, particularly a compressed air breathing apparatus, comprising a housing, which surrounds a pulmonary space for the breathing air and has a connection for supplying the breathing air to the breathing apparatus. In order to be able to variably control the volume flow for generating a certain respiration curve, the housing (2) surrounding the pulmonary space for the breathing air is provided with an inlet (5) and with an outlet (6) for the breathing air, a fan (7, 8) is connected to the inlet and outlet (5, 6), respectively, for supplying and removing the breathing air, and a cover (13), which can be actuated by way of a drive (16) and encloses the pulmonary space (3), is disposed in the housing (2), which cover controls the volume flow of the breathing air between the inlet (5) for the breathing air and the connection (4) for the supply of the breathing air to the breathing apparatus, and/or between the connection (4) and the outlet (6) for removing the breathing air, so as to generate the breathing curve.
