Transcranial Doppler Ultrasound for Monitoring the Cerebral Hemodynamic Changes and Prognosticating Outcomes in Venoarterial Extracorporeal Membrane-Oxygenated Patients

<div>The RMCA flow waveforms that can be observed during different cardiac functional states. (a) LVEF&lt;10%, the RMCA had an advection. (b) 10%&lt; LVEF &lt;20%, there was a systolic spike in the right middle cerebral artery. (c) 20%&lt; LVEF &lt;30%, the systolic peak of the RMCA increased further, but the PI was still below the normal value. (d) LVEF &gt;40%, the normal blood flow pattern of the RMCA.</div>
