Description
Summary:Figure 3 shows a representative sample of two SDs along with concurrent multimodal monitoring data, including the regional cerebral blood flow (rCBF), brain tissue oxygen, intracranial pressure, cerebral perfusion pressure, and pressure reactivity index. Data were captured by the bedside Component Neuromonitoring System (CNS) (Moberg Research Inc, Ambler, PA) using a full-band Advanced Amplifier (Moberg Research Inc). Because LFVFs are driven by electrical activity due to neurovascular coupling, their depression is a vascular manifestation of spreading depression. There was initially some mild brain tissue hypoxia (brain tissue oxygen 10–20 mm Hg) during the first 9 h of monitoring that resolved with augmenting cerebral perfusion pressure.
