COPD Awareness Month: The Importance of Early Detection and Lung Function Testing

Every November, COPD Awareness Month brings greater attention to chronic obstructive pulmonary disease (COPD), a progressive lung disease that affects millions of people and can make everyday activities increasingly difficult.

More than 30 million Americans are affected by COPD, yet approximately half remain undiagnosed, according to the COPD Foundation. Increasing awareness of the symptoms, risk factors, and importance of pulmonary function testing can help more people seek evaluation and receive appropriate care. [copdfoundation.org]

What Is COPD?

COPD is a term used to describe chronic lung diseases that cause persistent airflow limitation and difficulty breathing. It includes conditions such as emphysema and chronic bronchitis. [cdc.gov], [copdfoundation.org]

COPD typically develops over time, which can make the early signs easy to overlook. Common symptoms include:

• Shortness of breath, particularly during everyday activities
• Frequent coughing or wheezing
• Difficulty taking a deep breath
• Increased mucus or phlegm [cdc.gov]

While tobacco smoke is the leading cause of COPD in the United States, smoking is not the only risk factor. Secondhand smoke, environmental or occupational exposures, asthma, and family history can also contribute to COPD risk. [cdc.gov]

Why Early Detection Matters

Because COPD develops gradually, some people may adjust their daily activities as breathing becomes more difficult without realizing that an underlying lung condition could be responsible.

Recognizing symptoms and pursuing appropriate testing can help identify COPD earlier. The National Heart, Lung, and Blood Institute notes that spirometry can detect COPD even before symptoms are recognized. [nhlbi.nih.gov]

Although there is currently no cure for COPD, treatment and lifestyle changes can help reduce symptoms and improve quality of life. Accurate assessment of pulmonary function is an important part of understanding a patient's respiratory health. [cdc.gov]

The Role of Spirometry in COPD Diagnosis

Spirometry is the primary pulmonary function test used to diagnose COPD. The test measures how much air a person can exhale and how quickly that air can be expelled. [nhlbi.nih.gov]

Two important measurements obtained during spirometry are:

FEV1 (Forced Expiratory Volume in One Second): The amount of air that can be forcibly exhaled during the first second of the maneuver.

FVC (Forced Vital Capacity): The total amount of air forcibly exhaled after taking a full breath.

Together, these measurements help clinicians evaluate airflow obstruction. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) continues to identify spirometry as essential for confirming a COPD diagnosis. [goldcopd.org], [chestphysician.org]

Looking Beyond a Single Test

COPD assessment does not end with spirometry. Depending on a patient's symptoms and clinical needs, healthcare providers may use additional lung function and imaging tests to better understand respiratory health. [nhlbi.nih.gov]

The goal is not simply to identify airflow limitation, but to provide clinicians with objective information that can support informed patient care.

For pulmonary function laboratories, reliable respiratory diagnostic testing plays an important role throughout this process, from initial evaluation to ongoing assessment.

Supporting Better Respiratory Care

At MGC Diagnostics, we understand the important role pulmonary function testing plays in respiratory care. Providing clinicians with reliable diagnostic technologies helps support the objective measurements they need to evaluate pulmonary function and better understand their patients' respiratory health.

COPD Awareness Month is an opportunity to recognize the people living with COPD, the clinicians and respiratory professionals caring for them, and the importance of continued education and awareness.

This November, let's keep the conversation about lung health going and continue working toward earlier recognition, accurate testing, and better respiratory care.
