What is Spacer?
A tube that holds the inhaler puff so you do not need perfect timing. Use it every time with an MDI.
In real work
Your clinician may recommend a spacer so more medicine reaches your lungs.

Google gives a definition. Prompthaus pairs each term with how it shows up in standups, PRs, prompts, and design reviews—then quizzes you until the word sticks. One term a day on iPhone.
