Study Notes
Patient Presentation
- 90-year-old female patient.
- Complaining of increased breathlessness (dyspnea) over the past 6 months.
- 40-year history of smoking (10 cigarettes/day).
- GP suspects Chronic Obstructive Pulmonary Disease (COPD).
Emphysema Pathophysiology (related to smoking)
- Smoke inhalation causes lung damage leading to emphysema. The specific mechanism by which smoke causes damage to the lungs leading to emphysema is not stated.
Patient Presentation
- 90-year-old female patient.
- Complaining of increased breathlessness over the past six months.
- 40-year history of smoking (10 cigarettes/day).
- Physician suspects Chronic Obstructive Pulmonary Disease (COPD).
Emphysema Pathophysiology (due to smoke inhalation):
- Smoke inhalation causes damage to the lungs in multiple ways.
- One mechanism is the destruction of alveolar walls.
- This results in fewer, larger alveoli, reducing the surface area for gas exchange.
- This leads to the characteristic air trapping and reduced expiratory airflow in emphysema.
