Emphysema: Symptoms, Risk Factors, and First Aid Awareness in Canada
Emphysema is a chronic lung condition and a form of chronic obstructive pulmonary disease (COPD). It occurs when the air sacs in the lungs are damaged, reducing the lungs’ ability to exchange oxygen effectively. Over time, this leads to shortness of breath and reduced lung capacity.
In Canada, emphysema most commonly affects adults over the age of 45 and is strongly associated with smoking and long-term exposure to lung irritants.
Common Signs and Symptoms

The hallmark symptom of emphysema is gradually worsening shortness of breath, especially during physical activity.
Other symptoms may include:
- Chest tightness or pressure
- Chronic cough
- Wheezing
- Fatigue
- Increased mucus production
- Clubbing of the fingers or toes (in advanced cases)
Symptoms typically develop slowly and may not be noticed until lung function is significantly reduced.
What Causes Emphysema?
The primary cause of emphysema is smoking, including long-term exposure to secondhand smoke. Other contributing factors include:
- Prolonged exposure to dust, fumes, or chemical vapours
- Air pollution
- Occupational exposure in industries such as mining, agriculture, textiles, or manufacturing
- Rare inherited conditions affecting lung protection
These factors are relevant in many Canadian workplaces and environments.
Risk Factors
People at higher risk of emphysema include those who:
- Smoke or have a history of smoking
- Work in environments with airborne irritants
- Are exposed to air pollution or secondhand smoke
- Have pre-existing lung disease
- Have a family history of lung conditions
First Aid Awareness and Breathing Emergencies
Emphysema cannot be treated with first aid, but first aid awareness is critical for recognizing breathing distress and responding appropriately.
Seek immediate medical care if a person with emphysema experiences:
- Sudden or severe shortness of breath
- Blue or grey lips or fingernails
- Confusion or extreme fatigue
- Difficulty speaking due to breathlessness
Knowing how to recognize respiratory emergencies and respond calmly is a key part of first aid and CPR training in Canada.
Why This Matters for Canadians
Emphysema affects daily activities, workplace safety, and quality of life. For Canadians with chronic lung disease—or those caring for them—recognizing warning signs and responding early can prevent serious complications.
First aid education emphasizes early recognition, scene safety, and timely escalation, not diagnosis or medical treatment.
