What is a common physiological response during a laryngospasm?

• A. Increased heart rate
• B. Decreased heart rate
• C. Airway closure
• D. Increased respiratory rate

Answer: (C)

A common physiological response during a laryngospasm is airway closure. Laryngospasm occurs when the muscles around the larynx involuntarily contract, leading to a temporary blockage of airflow into the lungs. This reflex action can happen in response to irritants, excess secretions, or even as a protective mechanism to prevent foreign substances from entering the airways. During this episode, the vocal cords tightly close, resulting in the inability to breathe normally, which can be distressing for the individual experiencing it. Understanding this response is crucial for managing emergencies where laryngospasm is involved, especially in medical and clinical settings, as it can lead to significant respiratory distress if not addressed promptly. Other responses mentioned may occur in different contexts but do not specifically characterize the primary physiological reaction of airway closure during a laryngospasm.
