Orthopnea is a medical term used to describe shortness of breath that occurs when lying down flat. The spelling of the word is pronounced as /ˌɔːrθɒpˈniːə/ with the emphasis on the second syllable. The "o" in the first syllable is pronounced as a long "o," while the "a" in the second syllable is pronounced as a short "a." The final syllable is pronounced with a long "e" sound followed by an "uh" sound. The word is derived from Greek, where "orthos" means "upright" and "pnoē" means "breath."
Orthopnea is a medical term used to describe a particular symptom characterized by difficulty in breathing or shortness of breath when lying flat or in a horizontal position. It is a condition experienced by individuals who find it challenging to breathe properly unless they are in an upright or elevated position, such as sitting up or standing. People with orthopnea may feel more comfortable when propped up with pillows while sleeping or resting.
The term "orthopnea" is derived from the Greek words "ortho," meaning upright or straight, and "pnoia," meaning breathing or respiration. Orthopnea is often caused by an accumulation of fluid in the lungs, a condition known as pulmonary edema. This buildup of fluid may be a result of various underlying conditions, including congestive heart failure, chronic obstructive pulmonary disease (COPD), asthma, or obesity.
Orthopnea can lead to deep and rapid breathing, increased heart rate, and a sense of anxiety or distress due to the struggle to obtain adequate air supply. It is important for individuals experiencing orthopnea to seek medical attention to identify and address the underlying cause. Treatments for orthopnea differ based on the underlying condition causing it and may involve lifestyle modifications, medication management, or surgical interventions.
The word "orthopnea" is formed by combining two Greek words: "ortho", meaning "straight" or "upright", and "pnea", meaning "breath" or "breathing". So, "orthopnea" literally translates to "straight" or "upright" breathing.
