Medical Terminology Abbreviations

Medical abbreviations and EMT acronyms are needed to make charting faster and more efficient in the field. They also provide an accurate and precise way to communicate with other healthcare providers about the patient. Many EMT acronyms are universal, but often they vary by region and department. This page features common medical abbreviations and EMT terminology used by EMS personnel and Healthcare workers all over.

Here are a couple of examples of medical abbreviations and their meaning.

A very common question is:

What does EMT stand for? EMT stands for Emergency Medical Technician.

Another common question is:

What does EMS stands for? EMS stands for Emergency Medical Services.

First you can find a quick medical abbreviations list to scan at the top of this page. The bottom has a list with slightly more information and is separated by alphabet.

Some medical acronyms have different meanings in the medical field. For example, the CO abbreviation can mean both Cardiac Output and Carbon Monoxide. Other medical acronyms can mean something different depending on what medical professional you talk to or what area of the hospital you are in.

This page deals with Emergency Medical Response (EMS), Paramedic and EMT terminology. These are medical terms often used in the field and Emergency Department, and frequently seen in the patient’s chart.

Here are frequently asked questions about EMT terminology:

What does AOS stand for? Arrived on scene.
What does BSI stand for? Body Substance Isolation.
What does DOS stand for? Dead on scene.
What does IO stand for? Intraosseous.
What does Mg stand for? Magnesium.
What does mg stand for? Milligram.
What does mL stand for? Milliliter.
What does DOA mean? Dead on arrival.
What does DT mean? Delirium Tremens - which happen during alcohol withdrawal.
What is clr? Clear.
What is an EJ line? An IV line place in the External Jugular Vein.

V-fib and V-tach refer to cardiac arrhythmias.

PASG and the MAST medical term refer to pneumatic anti-shock garment and military anti-shock trousers. In most areas these are rarely used anymore.

And don’t forget that ACLS stands for Advanced Cardiac Life Support.
