What is the primary purpose of spirometry?

The primary purpose of spirometry is to identify changes in pulmonary function. This diagnostic test measures the volume of air that a patient can inhale and exhale, as well as the speed at which they can do so. By assessing these parameters, healthcare providers can determine the presence of various respiratory conditions, such as asthma, chronic obstructive pulmonary disease (COPD), and restrictive lung diseases. Changes in pulmonary function can indicate the progression of lung disease or the effectiveness of treatment, making spirometry a crucial tool in respiratory care.

While measuring blood pressure, evaluating heart rhythm, and examining mental health are all important aspects of overall health, they fall outside the scope of spirometry. This tool specifically focuses on respiratory function, highlighting its specialized role in diagnosing and monitoring pulmonary health.
