Introduction
What diagnostic tests are used for COPD? - Pulmonary function testing - Chest X-ray (helpful for evaluating changes in thoracic contour and detecting pulmonary fibrosis) - Chest spiral CT (primarily used for differential diagnosis; performed based on the patient’s clinical presentation) - Arterial blood gas analysis (indicated when disease exacerbation progresses to respiratory failure)

COPD generally refers to chronic obstructive pulmonary disease (COPD). COPD is a common chronic condition characterized by airflow obstruction, typically involving chronic bronchitis and/or emphysema. It may progress to cor pulmonale and respiratory failure. So, what diagnostic tests are used for COPD? Let’s explore them below.

Diagnostic Tests for COPD

Clinical evaluation of COPD includes the following tests: pulmonary function testing (PFT)—an essential test for both diagnosing COPD and assessing disease severity. A post-bronchodilator FEV1/FVC ratio <70% is generally considered diagnostic for COPD; FEV1 as a percentage of predicted value is commonly used to assess disease severity; chest X-ray (helpful for evaluating thoracic contour changes and detecting pulmonary fibrosis); high-resolution chest CT (primarily used for differential diagnosis—performed based on clinical presentation); and arterial blood gas analysis (particularly important when disease exacerbation progresses to respiratory failure).

Pharmacotherapy is the mainstay of COPD management. Although COPD cannot be cured, long-term medication helps preserve lung function. Commonly prescribed medications include short-acting beta2-agonists (e.g., salbutamol, terbutaline), anticholinergics (e.g., ipratropium bromide, tiotropium bromide), and inhaled corticosteroids (e.g., dexamethasone, budesonide, hydrocortisone) for patients unresponsive to initial therapy. Other options include methylxanthines (e.g., aminophylline) and mucolytics (e.g., carbocisteine, ambroxol, bromhexine). Regardless of symptom improvement, lifelong adherence to pharmacotherapy is essential.

Daily Care Strategies for COPD Patients

Patients with COPD must quit smoking completely. For those who have smoked for many years and find cessation difficult, it is advisable to gradually reduce cigarette consumption. Regular, moderate physical activity is encouraged to enhance immunity and improve lung capacity. Patients should reside in areas with clean, fresh air and avoid occupational environments with strong irritant odors or high levels of airborne dust.
