What tests should be done for lung examination

Pulmonary examination usually requires chest X-ray examination, lung function examination, blood oxygen saturation detection, chest CT examination, and bronchoscopy examination.

Chest X-ray examination is one of the most common lung examination items, which can help detect abnormal shadows, nodules, inflammation and other lesions in the lungs. Pulmonary function tests evaluate whether lung ventilation and air exchange function are normal by measuring indicators such as respiratory volume and expiratory flow. Blood oxygen saturation detection is a non-invasive examination method that can reflect the status of lung oxygenation function. Chest CT examination is more precise than X-ray and can detect early small lung lesions, especially suitable for screening high-risk populations. Bronchoscopy can directly observe the internal condition of the bronchi and perform further examinations such as biopsy or lavage.

It is recommended to maintain good lifestyle habits, quit smoking and stay away from second-hand smoke environments, engage in moderate aerobic exercise to enhance lung function, and reduce outdoor activities when the air quality is poor. Daily intake of foods rich in vitamin C and antioxidants, such as citrus fruits and broccoli, can help protect lung health. If symptoms such as persistent cough and difficulty breathing occur, seek medical attention promptly for follow-up examination.
