First Aid and Training abbreviations

List of First Aid Terms

The Medical field is full of Terms and Acronyms. Here we have compiled a list to help you understand some of the terminology, both medical and slang.

Clearly it is a work in progress as new terms are coming along all the time, but we hope that it will be of use to you.

Some of the slang terms may sound a bit callous, but consider the different traumas that frontline personnel will see on a regular basis. They need to develop a coping mechanism otherwise they would not be able to do their job effectively. Black humour is a way of coping.
