Anesthesia Jargon Translator & Glossary
Your anesthesia team may use shorthand that sounds like a foreign language. Type a word or abbreviation below and we will translate it into everyday language.
Frequently asked questions
Why does my team use so many abbreviations?
Anesthesia and surgery are fast-paced, so staff use shorthand to communicate quickly and precisely. It can feel like a different language. This glossary turns the most common terms into everyday language so you know what is happening to you or your loved one.
What does 'NPO' or 'nil by mouth' mean before surgery?
NPO (from the Latin 'nil per os') and 'nil by mouth' both mean nothing to eat or drink for a set time before your procedure. This keeps your stomach empty so food or liquid cannot come back up and enter your lungs while you are sedated. Always follow the exact fasting times your team gives you.
Is this glossary a substitute for talking to my anesthesia team?
No. It is an educational reference to help you understand the words you hear. Your anesthesiologist or nurse anesthetist knows your specific history and plan, so always ask them about anything that worries you and follow their instructions.
