Abstract:
Spirometry records breath movements, inhalation and exhalation, and is integral to the management of lung disease, alongside good history taking and careful documentation. Tests can indicate a patient's optimal response to treatment or triggers, and the rate of decline in lung function. It is useful to detect the presence of lung disease, those susceptible to developing lung disease and to classify patients into severity classifications to optimise management.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
