7. Stridor – A Distinctive Breathing Sound
Stridor is a loud, high-pitched breathing sound that is most noticeable during inhalation. It arises from turbulent airflow through the narrowed trachea, making it a distinctive and often alarming symptom of tracheal stenosis. Unlike wheezing, which typically occurs during exhalation, stridor occurs when breathing in, providing a clear auditory sign that the upper airway is obstructed.
The presence of stridor is a sign that the tracheal stenosis has reached a critical point. The narrowed airway not only produces this distinctive sound but also significantly restricts airflow, leading to increased respiratory effort. This can result in rapid fatigue and distress, particularly during physical activity or moments of exertion.
Stridor should be treated as a medical emergency, as it indicates a severe narrowing of the airway that requires immediate attention. If you or someone around you experiences stridor, seek medical help right away. Prompt intervention is crucial to ensure adequate airflow and prevent further complications. (7)
