How to Pronounce Peak Flow Meter

Say it like this: **PEEK FLOH MEE-ter**. The word "peak" rhymes with "week," "flow" sounds like the word "go," and "meter" has two syllables that sound like "MEE" and "tur." Put the stress on the first word: **PEEK** flow meter.

The stress falls on **PEEK**, the first syllable of the first word. People sometimes accidentally stress "flow" instead, but that's not correct. Remember: **PEEK** (stressed) flow MEE-ter (unstressed).

In this phrase, "peak" means the highest point or maximum amount. So "peak flow" refers to the strongest or fastest breath you can blow out. It's the same "peak" as in "mountain peak" — the top of something.

"Flow" means the movement or stream of something — in this case, air moving out of your lungs. You hear the same word in everyday speech when people talk about "traffic flow" or "water flow." Here it's about how air flows.

A "meter" is a tool that measures something. You've probably heard of a thermometer (measures heat) or a speedometer (measures speed). A peak flow meter measures how fast air comes out of your lungs, so "meter" is just the measuring part of the name.

Many people just call it a **peak flow** (say "PEEK FLOH") or shorten it to **PFM**. You might also hear healthcare workers say it's a "breathing measurement device," but "peak flow meter" is the official term.

Yes! "Spirometer" and "oximeter" are both medical devices with "meter" in the name. They follow the same pattern: a word describing what's being measured, plus "meter" for the tool that does the measuring. It's a common way to name measuring devices in medicine.

Here's how it splits up: **PEEK** (1 syllable) / **FLOH** (1 syllable) / **MEE-ter** (2 syllables). So altogether it's four syllables: PEEK-FLOH-MEE-TER. The stress lands hardest on the very first one.
