Cough Reflex Test (CRT) Practice Exam 2025 - Free CRT Practice Questions and Study Guide

The primary purpose of the Cough Reflex Test is to assess cough effectiveness in airway protection. This test evaluates how well an individual's cough reflex can clear secretions and protect the airways from potential pathogens or irritants. A strong cough reflex is essential for maintaining airway patency and preventing respiratory complications. Understanding how effectively a patient can cough is critical in various clinical scenarios, particularly in conditions like chronic obstructive pulmonary disease (COPD) or after surgical procedures, where the ability to clear secretions is necessary for recovery and to prevent infections.

In contrast, measuring heart rate response does not provide relevant information regarding airway protection. Determining lung capacity focuses on the volume of air that can be inhaled or exhaled, which, while related to respiratory health, does not directly assess the effectiveness of the cough reflex. Evaluating allergy responses pertains to how the immune system reacts to allergens, which is separate from the mechanical action of coughing to clear airways.
