Each entry gives more than the expansion. ABG is Arterial Blood Gas, the measurement of oxygen, carbon dioxide, pH, and bicarbonate from an arterial sample. ACS is Acute Coronary Syndrome, the umbrella term for STEMI, NSTEMI, and unstable angina. GCS is the Glasgow Coma Scale, scoring eye, verbal, and motor responses to a maximum of 15.

Entries are tagged by specialty, from cardiology and respiratory to neurology, critical care, haematology, and pharmacology, so you can filter to the terms that matter for your rotation or your exam and search instantly.

The glossary is built to be used quickly. When an abbreviation appears in a note, a question, or a handover, a single search returns the expansion together with the short clinical context that tells you why it matters.

All the glossary entries are open with no account, so it works as a free reference for students and doctors alike.
