Work out arterial blood gas interpretation instantly with clear inputs, formula shown and shareable results.
Classifies the primary acid-base disorder from pH, PaCO2 and bicarbonate, then tests respiratory compensation against Winter's formula.
Winter's formula
Expected PaCO2 = 1.5 x HCO3 + 8 (plus or minus 2) for a simple metabolic acidosis
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
It can still hide a mixed disorder, so PaCO2 and bicarbonate are checked even when pH is normal.
No. Anion gap, oxygenation, lactate and the clinical context are all needed for a complete reading.
