15. Coronary Perfusion Pressure (CPP)
Pulmonary Vascular Resistance Index (PVRI) (1)
Clinical Pearls for ICU Physicians
pulmonary artery pressure
oxygen extraction ratio (ERO₂) (1)
arteriovenous oxygen difference and its implication
VO₂, consumption of oxygen
Arterial Oxygen Content (CaO₂)
A–a gradient, and how is it interpreted
calculate Shunt Fraction via Fick Method
High SvO2 and low extraction suggest early septic shock)
High A-a gradient suggests shunt
Calculate QpQs
Calculate CaO2
shunt fraction (using Berggren)

5 minutes PICU
Cerebral Perfusion Pressure (CPP)
Mean Arterial Pressure (MAP)
Cerebral Oxygenation Index (COx)
intracranial Pressure Index (ICP Index)
Pressure Reactivity Index (PRx)

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
