Abstract: A process for operating a respiration system (3) makes it possible, rapidly and with simple means, to operate the respiration system (3). The system and method use respiratory flow sensor-specific, patient- and/or treatment-related operating data and a respiratory flow sensor (1). A reading unit present in the respiration system (3) reads the contents of a transponder (2) connected to the respiratory flow sensor (1), so that the respiration system (3) is ready to operate only after the operating data have been read.

Abstract: A water trap (1) for a breathing tube (2) includes a collection tank (3) for water of condensation and at least one device (4) for attaching the collection tank (3) to the breathing tube (2). The attachment is such that the water of condensation can be drawn off from the breathing tube (2) at any desired point of the breathing tube (2). The water trap (1) has at least one device (5) for preparing at least one opening in the breathing tube (2). The water trap (1) is manufactured at a low cost and makes safer and more reliable handling possible.
