Quad coughing is a technique used to assist individuals with weakened or absent coughing abilities by which action?

• A. Manually compressing the abdomen to create a forceful cough.
• B. Applying chest percussion to loosen secretions.
• C. Administering inhaled bronchodilators to improve cough.
• D. Using positive airway pressure to deliver cough.

Answer: (A)

Quad coughing boosts the force of a cough by increasing the pressure inside the chest during exhalation. When a caregiver applies firm, rapid pressure to the abdomen just below the diaphragm as the person breathes out, it raises intrathoracic and intra-abdominal pressure. This makes the expiratory flow stronger, helping to push secretions out of the airways that the weakened cough can’t clear on its own.

Other techniques, like chest percussion, focus on loosening secretions rather than generating a stronger cough. Inhaled bronchodilators help open airways but don’t directly produce a more forceful cough. While some devices use positive airway pressure to assist coughing, the classic quad coughing method relies specifically on manual abdominal compression to create that powerful cough.
