Expiratory apnea
Expiratory Apnea
Expiratory apnea (/ɛkˈspaɪrətɔːri ˈæpniə/), from the Greek words apnoia meaning "want of breath" and expirare meaning "breathe out", is a medical condition characterized by the cessation of airflow at the end of a normal or abnormal expiration.
Definition
Expiratory apnea is a type of sleep apnea where the person stops breathing during the expiratory phase of the respiratory cycle. This is in contrast to Inspiratory apnea, where the cessation of breathing occurs during the inspiratory phase.
Causes
Expiratory apnea can be caused by a variety of factors, including obstructive sleep apnea, central sleep apnea, and mixed sleep apnea. Other potential causes include certain medications, alcohol, and medical conditions such as heart failure and stroke.
Symptoms
Symptoms of expiratory apnea may include excessive daytime sleepiness, loud snoring, observed episodes of stopped breathing during sleep, abrupt awakenings accompanied by gasping or choking, awakening with a dry mouth or sore throat, difficulty staying asleep (insomnia), and attention problems.
Treatment
Treatment for expiratory apnea may involve lifestyle changes, such as losing weight or quitting smoking. In some cases, medical devices or surgery may be necessary. The specific treatment will depend on the underlying cause of the apnea.
