Essential Cerebrovascular Hemodynamics
The introduction of transcranial Doppler (TCD) has allowed for a relatively basic understanding of cerebral hemodynamics The technique has made evident the important effect of many variables, such as resistance, intracranial pressure (ICP), variations in partial pressure of carbon dioxide (CO2), and cerebral perfusion pressure (CPP), on cerebral blood flow velocities. The following is an overview of the most fundamental hemodynamic principles of TCD.
