Brain Monitoring: Do We Need a Hole? An Update on Invasive and Noninvasive Brain Monitoring Modalities

Figure 3

(a) Cortical cerebral blood flow (CBF) can be monitored with laser Doppler flowmetry, and CBF plotted against CPP shows the autoregulatory curve, called Lassen’s curve, with clear lower limit of autoregulation (LLA). ICP: intracranial pressure. ABP: arterial blood pressure. CPP: cerebral perfusion pressure. LDF: laser Doppler flowmetry. (b) Lassen’s curve. CPP: cerebral perfusion pressure. LDF: laser Doppler flowmetry.
