The invention relates to a medical system (1) with a monitoring station (3) and at least one medical work station (5, 7). The medical work station (5, 7) is designed to gather physiological data of a patient (4). The invention is characterized in that the at least one medical work station (5, 7) comprises a respiratory device (43, 60) with a connection (49, 51, 72, 74) for a respiratory hose (53, 57). The medical work station (5, 7) comprises a radio frequency detection unit (45, 68), which is designed for detecting a radio frequency marking (55) connected with a respiratory hose in the region of the connection for a respiratory hose, and to create a marking signal, representing the marking information. The medical system (1) is designed to associated the physiological data and the patient data, particularly the data set representing the physiological data and the patient data set, with each other, as a function of the marking signal.
