Respiratory tests are medical evaluations used to assess lung function and breathing efficiency. These tests help diagnose conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other respiratory disorders. Common types include spirometry, which measures how much air a person can inhale and exhale, and peak flow monitoring, which tracks the maximum speed of exhalation. Another important respiratory test is the pulmonary function test (PFT), which provides a comprehensive analysis of lung capacity and airflow. Additionally, imaging tests like chest X-rays and CT scans can help visualize lung structures and identify abnormalities. These tests are essential for guiding treatment and monitoring respiratory health.
