Abstract

A respiration system is provided, which has the greatest possible flexibility in operation based on a remote control (11), which is connected to a respirator (2) via separate data lines (9, 10) for display data and operating data. The display data are continuously displayed on both an operating unit (3) of the respiration system and the remote control (11). The operating data can only be entered either via the operating unit (3) of the respiration system or by the remote control (11).
