5 minutes PICU
Cerebral Perfusion Pressure (CPP)
Mean Arterial Pressure (MAP)
Cerebral Oxygenation Index (COx)
intracranial Pressure Index (ICP Index)
Pressure Reactivity Index (PRx)
Brain Tissue Oxygen Tension (PbtO₂ Index)
Jugular Venous Oxygen Saturation (SjvO₂)
Oxygen Extraction Fraction (OEF)
Lactate-Pyruvate Ratio (LPR)
Core CNS formulas PICU
Diagnostic Scenarios Based on CPP
Clinical Pearls for picu physician
DD with MAP, ICP, CPP
3-step approach CNS for physician
CPP and best interpretation
Cushing's triad signs indicate herniation risk)
ICP
PRx (Pressure Reactivity Index)
Hypoperfusion with cerebral hypoxia
ICP Index and its interpretation
Increase MAP using vasopressors
PbtO₂ 20 mmHg borderline hypoxia)
SjvO₂ 75% suggests reduced metabolism or hyperemia)
Steep pressure rise → poor compliance)
LPR and its interpretition
Oxygen Extraction Fraction (OEF), and what does it indicate
