INTRODUCTION. Evaluation of pulmonary function is important in many clinical situations, both when the patient has a history or symptoms suggestive of lung disease and when risk factors for lung disease are present, such as occupational exposure to agents with known lung toxicity [].The European Respiratory Society and the American Thoracic Society have published guidelines for the measurement. Pulmonary function test (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. Pulmonary function testing has diagnostic and therapeutic roles and helps clinicians answer some general questions about patients MedlinePlus: 003853.

Adults and children with lung diseases such as chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, cystic fibrosis (CF), or bronchopulmonary dysplasia (BPD) may require this therapy. Extra oxygen protects their bodies from the effects of low oxygen levels, helps them to function better, and allows them to stay more active. Adult. Home The nonspecific pulmonary function test: longitudinal follow-up and outcomes. Chest, 2011; 139:878-88. This study of nearly 1,300 patients sheds light on the commonly encountered combination of reduced FVC but normal FEV/FVC and TLC. Roughly 2/3 of patients maintained this pattern during a median of 3 years of follow-up while.

Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders. Pulmonary function tests include spirometry (which measures ventilation of the lungs), DLCO tests (which measure gas diffusion in the lungs), ABG tests (which measure the partial pressure of oxygen, PaO 2, and carbon dioxide, PaCO 2, in the arterial blood), and pulse oximetry (which measures oxygen saturation, SpO 2, of peripheral blood.
