From: The effect of Ventricular Assist Devices on cerebral autoregulation: A preliminary study
Real time, beat-to-beat traces of arterial blood pressure (BP) and cerebral blood flow velocity (CBFV) with a ventricular assist device (VAD). Upper channel: arterial BP waveform in a patient supported with a VAD, showing irregular fluctuations; middle channel: CBFV (insonated at the level of middle cerebral artery) with fluctuations transmitted from arterial BP; lower channel: electrocardiogram (ECG).
