Pulmonary function assessment through spirometry

Detailed explanation-1: -In pulmonary function testing, a postbronchodilator FEV1/FVC ratio of <0.70 is commonly considered diagnostic for COPD. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) system categorizes airflow limitation into stages. In patients with FEV1/FVC <0.70: GOLD 1-mild: FEV1 ≥80% predicted.
Detailed explanation-2: -The most effective and common method for diagnosing COPD is spirometry. It’s also known as a pulmonary function test or PFT. This easy, painless test measures lung function and capacity.
Detailed explanation-3: -Diagnostic spirometry is the ‘gold standard’ for diagnosing fixed airway obstruction and is essential for the early staging and treatment of COPD.
Detailed explanation-4: -Lung (pulmonary) function tests. These tests measure the amount of air you can inhale and exhale, and whether your lungs deliver enough oxygen to your blood. Chest X-ray. A chest X-ray can show emphysema, one of the main causes of COPD . CT scan. Arterial blood gas analysis. Laboratory tests. 15-Apr-2020
