Abstract

A system for respiration-controlled application of aerosol in powder form during artificial respiration or assisted respiration of a patient including an interface contacting the patient's respiratory tract, a unit for generating a respiratory gas flow, at least one inspiration line through gas flow is conducted to the interface, an aerosol generator, at least one aerosol line through which the generated aerosol is conducted from the aerosol generator to the interface, and a respiration sensor that detects the patient's respiration signal. A valve in the at least one aerosol line is controlled based on the detected respiratory signal. An intermediate store for generated aerosol in powder form is arranged between the valve and the aerosol generator. The gas flow has a first pressure that is higher than or equal to ambient pressure and the aerosol has a second pressure that is higher than or equal to the first pressure.
