What are the benefits of using transcranial Doppler techniques to investigate the potentially deleterious effects of CPB on cerebral hypop- fusion or embolic events?
Transcranial Doppler techniques offer several benefits in investigating the potentially deleterious effects of CPB on cerebral hypop- fusion or embolic events. These techniques allow for direct visualization of blood flow in the brain, allowing clinicians to more accurately assess the risk of cerebral ischemia. Additionally, the Doppler techniques can provide real-time feedback regarding cerebral vasomotor reactivity, providing insight into the effects of interventions such as increasing or decreasing CPB flow or altering the fraction of inspired oxygen. Finally, the Doppler techniques can provide insight into the risk of emboli, such as air or calcific debris, which can be difficult to detect via other methods.
