Abstract

A respiration system for noninvasive respiration includes a respiration drive, which is controlled by a control device, and includes a patient module (4) with electrodes for picking up electrode signals from the surface of the chest of a patient. The control device is set up to suppress ECG signals in the electrode signals in order to obtain electromyographic signals (EMG signals) representing the breathing effort and to control the respiration drive as a function of the EMG signals. Provisions are made for deriving ECG signals from the electrode signals before said ECG signals are suppressed and for making data representative of the ECG available for display.
