A respirator for respiration of a patient having an interface (3) for input of at least one respiration parameter (PINSP, PEEP, RAM, I/E, RAT, TINSP, TEXP, TAZ) which is relevant for the respiration is provided. According to the invention, the respirator comprises a computation unit for calculating a respiration curve (4, 4a, 4b) from the at least one respiration parameter (PINSP, PEEP, RAM, I/E, RAT, TINSP, TEXP, TAZ) and a display unit (2) for display of the calculated respiration curve (4, 4a, 4b). In addition, a method for operation of the inventive respirator is provided.
