The invention is relative to a method and an apparatus for supporting the
respiration of a patient and to a tracheal
prosthesis. According to the invention the
spontaneous respiration of a patient is detected by sensors and at the end of an
inhalation procedure an additional amount of
oxygen is administered to the lungs via a jet gas current. This improves the absorption of
oxygen during
inhalation. If required, the
exhalation procedure of the patient can be arrested or slowed by a countercurrent in order to avoid a collapse of the
respiration paths in this manner. This procedure is realized by an apparatus comprising an
oxygen pump that can be connected to an oxygen source and comprising a tracheal
prosthesis that can be connected via a
catheter. The
spontaneous respiration of the patient is detected by sensors connected to a
control unit for activating the oxygen pump. The tracheal
prosthesis comprises a tubular support body with a connection for the
catheter and two of the sensors are associated with the support body. The tracheal prosthesis and the jet
catheter that is integrated or can be introduced are dimensioned so that the patient can freely breath and speak without restriction.
