👉 Apnic fluid, also known as apneic cough or post-apneic cough, is a condition characterized by an abnormal cough that occurs shortly after a person stops breathing during sleep, typically during episodes of obstructive sleep apnea (OSA). This cough can be triggered by the sudden re-expansion of the airways as oxygen levels rise after the cessation of breathing, leading to irritation and inflammation of the throat and airways. The exact mechanism is not fully understood but involves a combination of factors including increased airway sensitivity, inflammation, and possibly a reflexive response to the change in oxygen levels. Apnic fluid can be a significant symptom of sleep apnea, indicating potential respiratory distress and contributing to daytime fatigue and other health issues if left untreated.
