Figure 3. Representative recordings of MABP, V^mca, and EEG in a patient anesthetized with 1.5 MAC isoflurane. V^mcais coupled to brain activity during burst suppression such that the onset of a burst results in a substantial increase in V^mca, which is maintained for the duration of the burst. (insonation depth, 60 mm; ETCO², 42 mmHg; nasopharyngeal temperature, 35.7 [degree sign] Celsius).
