"In the clinic, the patient reported orthopnea, noting difficulty breathing when lying down."
"The physician asked about orthopnea to assess heart failure risk."
"Orthopnea can necessitate adjusting sleeping position or using additional support devices."
Orthopnea is pronounced or-tho-PNEA, with primary stress on the third syllable. IPA: US ˌɔrˈθɒpniə, UK ˌɔːˈθɒpniə, AU ˌɔːˈθɒpniə. Start with the 'or' as in 'or,' then 'tho' with a voiceless dental fricative /θ/, followed by 'p' plus 'nee-uh' (/pniə/). The final syllable is a schwa-like /ə/.
Common mistakes include misplacing the stress (thinking it’s on the first syllable), pronouncing /θ/ as /t/ or /s/, and pronouncing the final /ə/ too short or as /æ/. Correct approach: stress the third syllable: or-tho-PNEA. Use the dental fricative /θ/ in the 'tho' portion and end with a light schwa /ə/. Practice with minimal pairs to lock the placement of /θ/ and /niə/.
In US English you’ll hear /ˌɔːrˈθɒpniə/ with a rhotacized 'or' and a clearer /ɒ/ in the second syllable. UK English tends toward /ˌɔːˈθɒpniə/ with less rhoticity on the initial vowel and a shorter /ɒ/ in the second syllable. Australian tends to /ˌɔːˈθɒpniə/ with similar vowel qualities to UK but often a slightly broader vowel in stressed syllables and a mild non-rhoticity. All share the /θ/ in 'tho' and final /ə/.
The difficulty centers on the sequence /θ/ (the dental fricative) after a vowel, which is relatively rare in many languages; the cluster /θp/ is awkward, and the final /niə/ reduces to a light /niə/ or /nɪə/, requiring careful lip-tongue coordination. Maintain steady tempo so you don’t run the 'p' into the 'n' and ensure the tongue lightly touches the upper teeth for /θ/. The multi-syllable structure with stress on the penultimate or antepenultimate adds to the challenge.
There are no silent letters in Orthopnea, but the primary stress falls on the third syllable: or-tho-PNEA. The 'PNEA' portion carries the beat in most pronunciations, with the /n/ and /j/ sequence: /p-niə/. The key is not to overshoot the /θ/ and to keep the /ə/ at the end light. Its multisyllabic, medical nature makes speakers pause before the final syllable.

Orthopnea derives from Greek orthos ‘straight, right, correct’ and pnoia from pnein ‘to breathe.’ The term was adopted into medical vocabulary as clinicians sought precise descriptors for breath-related symptoms that are position-dependent. The early use appears in 19th-century medical literature as cardiac and pulmonary pathologies were increasingly associated with positional dyspnea. The combination of orth- (straight) and -pnea (breath) directly encodes the symptom: breathing difficulty that becomes evident in a straight/seated or upright posture and worsens when the body is recumbent. Over time, orthopnea has remained a specific clinical sign, differentiated from exertional dyspnea or paroxysmal nocturnal dyspnea, to guide diagnostic pathways and treatment considerations, including diuresis, nocturnal ventilation, or cardiac intervention. Its usage spans patient education, case reports, and cardiopulmonary assessments, preserving the original emphasis on body position in breathing comfort.
