From: Intracranial pressure for clinicians: it is not just a number
Plateau wave in a TBI patient. abp: arterial blood pressure; icp: intracranial pressure; rso2_l: brain oxygen saturation collected with near infrared spectroscopy, left side; rso2_r: brain oxygen saturation, right side; fvl: flow velocity left acquired with transcranial doppler; fvr: flow velocity right. On the left (A) raw signals collected during multimodal monitoring in ICU. On the right side, the same raw signals are represented as means over 10 s. While ICP increases, it is possible to see that flow velocity decreases in both sides, as well as the brain regional oxygen saturation
