Observed annually on the third Wednesday in November, World COPD Day serves as a pivotal moment to raise awareness about Chronic Obstructive Pulmonary Disease (COPD), a progressive lung disease that affects millions of people worldwide.
The 2024 theme for World COPD Day is “Know Your Lung Function." World COPD Day takes place on November 20th. This year's theme aims to highlight the importance of measuring lung function, also known as spirometry. Although spirometry is an integral tool for diagnosing COPD, it can also be used to measure lung health throughout life. We now know that there are many other factors besides tobacco smoke that can contribute to COPD. Our lungs are continuing to grow, from the womb all the way through young adulthood. Throughout this period we are vulnerable to insults such as air pollution and respiratory infections that can impede lung growth and increase our risk for developing chronic lung disease later in life. Unfortunately, much lung function can be lost before we develop symptoms. Lung function is a not only a predictor of lung health, but our overall health. Even small decrements in lung function are associated with increased risk of death. Measuring lung function throughout life can provide opportunities for early diagnosis and prompt treatment of multiple lung diseases, including COPD.
COPD, characterized by persistent airflow limitation, often results from long-term exposure to harmful particles or gases, such as cigarette smoke, air pollution, and occupational dusts. The primary symptoms include chronic cough, excessive mucus production, shortness of breath, wheezing, and chest tightness. As the disease progresses, patients may experience hypoxemia, a condition where the oxygen levels in the blood are lower than normal, leading to fatigue, confusion, and even life-threatening complications.
This year, as we mark World COPD Day, it is essential to underscore the role of oxygen concentrators in managing this chronic condition, which can significantly improve the quality of life for those living with COPD.
Oxygen therapy is a cornerstone of COPD management, particularly for those with severe hypoxemia. It involves delivering supplemental oxygen to the patient through various devices, including nasal cannulas, face masks, and, increasingly, oxygen concentrators.
