Signs of laryngospasm include inspiratory stridor, characterized by a high-pitched sound while inhaling, and potential sudden, complete airway obstruction. While shortness of breath and wheezing are often observed, they are not unique to laryngospasm.
With laryngospasm, a condition marked by reflex contraction of the muscles of the larynx (including the vocal cords), several signs and symptoms can be observed. Among these are:
- Inspiratory stridor: This high-pitched, wheezing sound is typically heard when inhaling and indicates a narrowing of the airway due to laryngospasm.
- Sudden, complete airway obstruction: Laryngospasm can cause the airway to close suddenly, making it extremely difficult or impossible to breathe.
Other symptoms associated with conditions affecting the airways, such as shortness of breath, wheezing, cough, and sensations of swelling or tightness in the throat, may also be present, though these are not uniquely indicative of laryngospasm.
