Hypopnea
Hypopnea
Hypopnea (pronounced: hi-POP-nee-uh) is a medical term that refers to abnormally slow or shallow breathing. The term is derived from the Greek words 'hypo' meaning 'under' and 'pnoia' meaning 'breath'.
Definition
Hypopnea is characterized by a decrease in airflow for 10 seconds or more, leading to a 30% reduction in ventilation. This condition is often associated with sleep apnea, a disorder in which breathing repeatedly stops and starts during sleep.
Symptoms
Symptoms of hypopnea may include daytime sleepiness, fatigue, morning headaches, and difficulty concentrating. It is often identified through a polysomnography, a type of sleep study.
Causes
Hypopnea can be caused by a variety of factors, including obesity, smoking, alcohol or sedative use, and certain medical conditions such as asthma or COPD.
Treatment
Treatment for hypopnea often involves lifestyle changes such as weight loss, quitting smoking, and avoiding alcohol and sedatives. In some cases, medical devices such as CPAP machines or surgery may be recommended.
