Certified Respiratory Therapist Practice Exam

Question: 1 / 400

What is the purpose of a spirometry test?

Assess lung function

The purpose of a spirometry test is to assess lung function by measuring how much air a person can inhale and exhale, as well as how quickly they can do so. This diagnostic tool is critical in evaluating conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other disorders that affect breathing. By providing detailed information about lung volumes and airflow rate, spirometry helps healthcare providers determine the presence and severity of respiratory conditions, enabling them to tailor appropriate treatment plans for patients.

While measuring blood oxygen levels, evaluating gas exchange efficiency, and checking for respiratory infections are important aspects of respiratory health, these functions are typically assessed through different tests and methods rather than through spirometry, making the focus on lung function the correct choice.
