Which neuromonitoring modalities assess cerebral perfusion and intraoperative depth of anesthesia, and what do their results imply?

Which neuromonitoring modalities assess cerebral perfusion and intraoperative depth of anesthesia, and what do their results imply?

• A. SpO2 monitoring; ECG; arterial line waveform; all prompt nothing.
• B. Cerebral oximetry (rSO2) regional oxygenation; Transcranial Doppler flow velocities; EEG/BIS depth; abnormal values prompt perfusion and depth optimization.
• C. Intracranial pressure; jugular venous oximetry; nerve monitoring; values prompt repositioning.
• D. Fundamental muscle tone; reflex testing; near-infrared reflectance; values prompt anesthesia depth changes.

Answer: (B)
