ABG Interpreter & Practice

How do you read an arterial blood gas — is it respiratory or metabolic, acidosis or alkalosis, and is it compensated? ABG Interpreter is a study tool that makes the pattern automatic for respiratory-therapy and nursing students. Type the three numbers from any ABG problem — pH, PaCO2 (mmHg), and HCO3 (mEq/L) — and it names the primary disorder and the compensation, and shows exactly how it got there. INTERPRET - The full answer in plain words: "Partially compensated respiratory acidosis," "Fully compensated metabolic alkalosis," and the rest. - A colour-coded read on each value — coral for acid, azure for base, slate for normal — so you can see which one is driving the pH. - A pH-spectrum bar that marks where your pH sits against 7.35, 7.40, and 7.45. - The ROME walk-through, one row at a time: pH, then PaCO2, then HCO3, then the primary disorder, then the compensation — the reasoning, not just the label. - Tap a worked example to fill the fields, or copy the whole interpretation as text. DRILL - Practice endlessly or take a scored test of 5, 10, 20, or 30 cases. - Read the values, pick the interpretation from four options, and get immediate feedback with the full breakdown. - Score, streak, best streak, and average time per case, with a graded results screen and a private on-device history. HONEST BY DESIGN - 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 — telling them apart needs the clinical picture, which is beyond a study tool. - Values that can't fit any pattern are flagged "re-check your entry," never force-labelled. - Every rule and range is standard, published material, cited in the in-app Guide (StatPearls; Berend et al., NEJM 2014; the ROME method). This is student study and exam-prep software, not clinical decision support. It classifies the numbers you enter using textbook rules — it does not diagnose, does not know your patient, and must never be used to guide real care. Always follow your program, your institution's protocols, and a qualified clinician's judgment. Verify every result independently. - One-time purchase.
