What typically occurs during paradoxical vocal fold motion incidents?

• A. Complete vocal cord relaxation
• B. Inhalation accompanied by wheezing or stridor
• C. No effect on blood oxygen levels
• D. Consistent airflow with no obstruction

Answer: (B)

During paradoxical vocal fold motion incidents, the vocal folds are incorrectly adducted (brought together) during inhalation rather than abducted (opened) as they should be. This can lead to symptoms such as wheezing or stridor, which are indicative of airway obstruction. The abnormal positioning of the vocal folds restricts airflow into the lungs, causing the characteristic high-pitched sounds associated with these conditions. This event can create an acute feeling of breathlessness due to the inability to properly inhale, resulting in increased respiratory distress.

The other options do not accurately represent the physiological changes that occur during these incidents: complete relaxation of the vocal cords would not contribute to the symptoms experienced; any obstruction typically affects blood oxygen levels if severe; and airflow is notably not consistent but rather obstructed during these episodes.
