The ABG interpretation guide

Thirty free ABG practice cases with the answer worked step by step, plus the method, the normal values, the compensation rules, Winter’s formula, worked examples and an FAQ. Every clinical fact links to the Merck Manual or MedlinePlus page it comes from.

What it is

ABG interpretation in two taps. Type pH, PaCO2 and HCO3 and the app names the answer in plain words — "partially compensated respiratory acidosis", "fully compensated metabolic alkalosis" — with the ROME walk-through that got there, one row at a time: pH, then PaCO2, then HCO3, then the primary disorder, then the compensation. Then drill graded cases until the pattern is automatic, endlessly or as a scored test of 5, 10, 20 or 30.

Why we built it

Respiratory-therapy and nursing students have to read an arterial blood gas on an exam and on a floor, and the tools that exist either hand back a label with no reasoning or bury it in a subscription. This shows the reasoning, not just the answer, and it is honest about the limits: a normal pH with opposing abnormal values is read as full compensation, and the app tells you plainly that the same numbers can also mean a mixed disorder. Study and exam-prep software, not clinical decision support.

ABG Interpretation & Practice is one of 17. We can build yours.

Every app on the shelf started as one honest problem, scoped small and built native, end to end. That’s exactly how we approach client work — designed, built and shipped, without the bloat.
