Respiratory artifact on EEG independent of the respirator.

Recognizing EEG artifacts is important to correctly interpret and avoid unnecessary intervention. EEG artifacts from mechanical ventilation have been described as periodic, frontally maximal high amplitude waveforms, occurring at the same rate as the ventillator. Here, we describe a non-periodic respiratory artifact that was independent of the ventilator rate. The concomitant use of audio was helpful in identifying this artifact.
