What is laryngospasm?

Laryngospasm is best defined as a form of airway obstruction that occurs when the vocal cords suddenly constrict or spasm. This reaction can temporarily block the airway, making it difficult for a person to breathe, speak, or make sounds. It is often a protective reflex of the body that can occur in response to irritants or during situations where the airway is threatened.

Understanding the nature of laryngospasm is critical, especially in contexts like moderate sedation where maintaining an open airway is essential for patient safety. In cases of laryngospasm, patients may exhibit stridor or wheezing sounds, indicating difficulty in airflow, and if severe, it can necessitate immediate medical intervention.

Recognizing that laryngospasm is not merely a throat irritation, a temporary cessation of breathing, or a respiratory infection clarifies its clinical implications. It is more serious than these other options and requires prompt recognition and management to prevent potential complications resulting from airway obstruction.
