What it does
Provides a first-pass study interpretation of arterial blood gas values and shows expected-compensation estimates. It cannot establish a complete acid–base diagnosis.
How to read it
Normal ranges: pH 7.35–7.45, PaCO₂ 35–45 mmHg, HCO₃ 22–26 mEq/L. Read the pH for acidosis or alkalosis, match the respiratory (CO₂) or metabolic (HCO₃) value that is driving it, then check whether the other value has shifted to compensate.
Worked example
For a study case with pH 7.30, PaCO₂ 55 mmHg and HCO₃ 26 mEq/L, the tool reports respiratory acidosis, compatible with the acute compensation estimate. Expected HCO₃ is about 25.5 mEq/L by the acute teaching estimate; clinical timing still needs confirmation.
Good to know
A near-normal pH does not prove that a disorder is fully compensated. Confirm expected ranges, sample consistency and possible mixed disorders against the clinical reference and the study question’s assumptions.
Study calculations only, not dosing recommendations. Real medication orders and administration require the appropriate clinical checks and facility protocol.
