A method and device for determining the validity of a respiratory effort waveform from a signal having non-respiratory artifacts includes monitoring a respiratory effort waveform for a parameter of the waveform that is characteristic of a non-respiratory artifact. The parameter is then compared with a predetermined limit to determine whether a valid respiratory waveform has been detected. This is useful for obstructive apnea treatment by electrical stimulation in order to reliably limit electrical stimulation to the inspiratory phase of the respiratory cycle. |
