How to Pronounce Rales

Rales is pronounced RAHLZ, rhyming with the word 'pals.' It's a one-syllable word, so you say the whole thing as one sound: RAHLZ.

Many people mistakenly pronounce it as 'rails' (like train rails) or 'reels,' but the correct way is RAHLZ—with a short 'ah' sound like in 'calm' or 'palm.' Remember: RAHLZ, not rails.

Rales describes unusual crackling or rattling sounds that doctors hear when they listen to someone's lungs with a stethoscope. Think of it like the sound of Velcro being pulled apart—it's an abnormal noise that shouldn't be there.

Rales comes from an old French word meaning 'rattle' or 'rattling sound.' Medical professionals borrowed this French word because it perfectly describes the sound itself—a rattling or crackling noise in the lungs.

Yes, doctors still use 'rales,' though many now prefer the term 'crackles' because it's more descriptive and easier to understand. Both words mean the same thing and refer to those abnormal lung sounds.

You might hear a doctor say: 'The patient has bilateral rales heard at the lung bases,' which means abnormal crackling sounds are present in both lungs at the bottom. Or simply: 'We detected rales when listening to his chest.'

Both are abnormal lung sounds heard with a stethoscope, but 'rales' (RAHLZ) are crackling or popping sounds, while 'rhonchi' (RONG-kye) are wheezing or buzzing sounds. They're different types of abnormal sounds that doctors listen for.

Rales is just one syllable: RAHLZ. There's no need to break it up into smaller parts because you say it all as one sound with the short 'ah' vowel sound in the middle.
