EASy IVC/PDA

Pre-Induction Optimization Protocol

EASy IVC/PDA combines IVC assessment with the hemodynamic cluster framework to guide pre-induction optimization of critically ill patients. This protocol integrates the PDA airway risk assessment with targeted volume and vasopressor management.

Protocol Components

IVC diameter measurement (2cm from RA junction)

IVC collapsibility index calculation

Hemodynamic cluster identification (1-4)

Pre-induction fluid optimization targets

Vasopressor/inotrope recommendations by cluster

Post-induction reassessment protocol

IVC-Guided Optimization

Small (<1.5cm), collapsing

Volume resuscitate before induction

High risk of post-induction hypotension

Normal (1.5-2.5cm), partial collapse

Small fluid bolus, prepare vasopressor

Moderate risk

Plethoric (>2.5cm), no collapse

Avoid fluid, assess RV/LV function

May indicate cardiogenic or obstructive cause
