ABG and VBG

ABG and VBG interpretation, worked out and explained

Critical Med’s ABG calculator interprets arterial and venous gases step by step. Enter pH, PaCO₂ and HCO₃⁻ and it works out the primary disorder, compensation, anion gap, base excess and Winter’s formula, then explains the reasoning in plain language. It’s an educational reference, not a diagnostic device.
