What is the primary purpose of pulmonary function tests?

The primary purpose of pulmonary function tests is to assess lung function and diagnose respiratory diseases. These tests measure how well the lungs work by evaluating airflow, lung volume, and gas exchange capabilities. They provide critical information about the presence of conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other restrictive or obstructive lung diseases. By quantifying different aspects of lung function, healthcare providers can make accurate diagnoses, monitor the progression of lung diseases, evaluate the effectiveness of treatments, and plan appropriate interventions. The comprehensive data gathered from these tests aids in understanding the severity of respiratory conditions and assists in decision-making about potential therapies.
