A respiration device with a respirator (3) and a sensor unit (8) close to the patient has a display unit (7) for measured parameters, with a breathing gas tube (5) between the respirator (3) and the sensor unit (8). A bidirectional data connection is provided between the sensor unit (8) and the respirator (3). The physiological measured values important for the respiration are recognized in the vicinity of the patient in a need-adapted manner. A configuration device is provided, by which presettable display fields can be set for the measured parameters on the display unit (7).
