I’m an emergency medicine doctor in Australia, and I’ve been building ABG Master — a structured learning and practice platform for blood gas interpretation.
I found plenty of calculators, summaries, and static teaching pages, but not many tools centred on repeated clinical practice, feedback, and progression.
The core of ABG Master is a physiology-first practice case engine. Cases are designed so the numbers make sense, compensation is plausible, and people learn the reasoning rather than just getting a label.
The practice cases scale across 4 difficulty levels:
- Clear disorders early on
- Less obvious clinical clues as you progress
- More variation in the numbers
- More reasoning required at higher levels
- Mixed disorders, which are often underrepresented in other resources
The are currently learning modules, practice cases, step-by-step feedback, basic progress tracking (for now), XP-style progression, and early minigame-style learning interactions.
More cases will be added. The current cases are curated carefully for testing, but I have plans to add hundreds of cases across many different scenarios.
The main things I’m trying to improve are:
- whether the practice flow feels intuitive
- whether explanations are clear
- whether the difficulty progression feels fair
- whether the app feels polished enough to keep using

Happy to hear any feedback, criticism, or ideas. Thanks!
