Lung function tests are diagnostic assessments conducted to evaluate the capacity of the lungs in terms of airflow movement, speed, and efficiency. These tests involve breathing into a specialized device designed to measure various parameters of respiratory function. By assessing how much air the lungs can inhale and exhale, as well as the speed and effectiveness of these actions, lung function tests provide valuable insights into pulmonary health and help diagnose respiratory conditions. This non-invasive procedure aids healthcare professionals in understanding the functioning capacity of the lungs and guiding appropriate treatment strategies.
