Enter arterial pH (6.5–8.0), PaCO₂ (mmHg), and HCO₃⁻ (mEq/L). PaO₂ is optional. The app classifies the primary disorder (respiratory/metabolic acidosis or alkalosis), assesses compensation using Winters' formula for metabolic acidosis, or acute/chronic rules for respiratory disorders, and flags mixed disorders.
Enter Na⁺, Cl⁻, and HCO₃⁻ in mEq/L. Albumin (g/dL) is optional — when provided, an albumin-corrected AG is shown (add 2.5 per 1 g/dL below 4.0). The delta ratio (AG excess / HCO₃ deficit) helps identify mixed HAGMA and NAGMA disorders.
Enter serum lactate in mmol/L or mg/dL (tap the unit button to convert). Normal is <2 mmol/L; hyperlactatemia 2–3.9; lactic acidosis ≥4. Optionally enter systolic BP for shock classification using Sepsis-3 / cryptic shock criteria.
Enter PaO₂, PaCO₂, and FiO₂ (as a fraction, e.g. 0.21 for room air). Use the quick preset buttons for common FiO₂ values. P/F ratio is classified by the Berlin ARDS definition. A-a gradient requires age to calculate the age-adjusted upper limit of normal (age/4 + 4).
