The importance of annual lung function testing for COPD patients

COPD patients are well aware of the challenges of living with a respiratory condition: in addition to breathing difficulties and constant fatigue, conditions such as emphysema or chronic bronchitis can affect mental and emotional health and limit independence.

It is therefore clear that the long-term management of this condition cannot stop at diagnosis alone. Among the most effective strategies for coping with COPD is regular monitoring, which allows treatment adjustments to be made promptly.

In this article, we examine the importance of annual lung function testing for COPD patients.

What is COPD?

COPD, or Chronic Obstructive Pulmonary Disease, is a progressive lung condition in which damage to the lungs causes swelling and inflammation, leading to airflow obstruction and limiting the movement of air into and out of the lungs.

It is most often caused by long-term exposure to irritants such as smoke, fumes, allergens, or chemicals, and it leads to symptoms including cough, shortness of breath, and wheezing.

The most common types of COPD are:

• Chronic bronchitis, in which the lining of the airways becomes inflamed and produces excess mucus
• Emphysema, where the tiny air sacs in the lungs, known as alveoli, are permanently damaged, making the exchange of oxygen and carbon dioxide more difficult

Why annual lung function tests are crucial for COPD patients

Lung function tests, also known as pulmonary function tests or PFTs, play a key role in the long-term management of COPD for several reasons, including:

• They provide objective data on lung function. Rather than relying solely on patient-reported symptoms, tests such as spirometry provide precise measurements of airflow and lung volume, enabling physicians to tailor treatments based on reliable data
• They detect functional decline before symptoms worsen. Lung function deterioration is not always immediately noticeable. Objective measurements help predict future exacerbations and assess mortality risk
• They allow for treatment adjustments. Lung function tests can show whether airflow improves with bronchodilators, guiding medication choices and therapeutic strategies

This is why COPD patients are encouraged to schedule PFTs at least once a year to monitor their condition.

Which pulmonary function tests are used in COPD monitoring?

What are the most commonly used pulmonary function tests during annual check-ups for COPD patients?

Spirometry is the gold standard for both the diagnosis and monitoring of COPD. Its main parameters (FVC, FEV₁, and the FEV₁/FVC ratio) measure how much air a patient can exhale and how quickly, providing insight into lung capacity and the presence and severity of airflow obstruction.

Other commonly used tests include lung volume measurements and diffusing capacity tests for carbon monoxide (DLCO), which assess how effectively carbon monoxide diffuses from the lungs into the bloodstream and provide information about gas exchange efficiency.
