Study Notes
Chronic Obstructive Pulmonary Disease (COPD)
- Characterized by chronic dyspnea and expiratory airflow limitation that remains relatively stable.
- A slowly progressive, preventable, and treatable respiratory disease involving airflow obstruction in airways and pulmonary parenchyma.
- Includes a combination of emphysema and chronic bronchitis, creating a group of chronic inflammatory lung diseases.
- Classified as irreversible with progressive nature.
Emphysema
- Involves damage and rupture of alveolar inner structures.
- Presents as silent chest sounds in patients, often older and thinner.
Chronic Bronchitis
- Characterized by a smoker’s cough, inflammation, and fibrosis of the bronchial lining.
- Known as "blue bloaters" due to CO2 retention leading to peripheral edema and potential right-sided heart failure.
- Defined by clinical features, with overweight patients more susceptible to complications.
Diagnostic Tests for COPD
- History taking and physical examination are fundamental first steps.
- Chest X-ray (CXR) and arterial blood gas (ABG) testing are essential for assessment.
- Pulmonary Function Test (PFT) including spirometry is critical for evaluating airflow obstruction.
- Alpha 1 antitrypsin levels and CT scans aid in differential diagnosis.
- Six-minute walk test helps gauge exertional dyspnea, with normal individuals showing little breathlessness while COPD patients exhibit notable difficulty.
Causes of COPD
- Smoking is the primary cause, damaging respiratory cilia and leading to chronic irritation.
- Respiratory viruses (e.g., influenza, rhinovirus) and bacteria (e.g., Bordatella, Haemophilus influenzae) contribute to airway infections.
- Alpha 1 anti-trypsin deficiency compromises lung protection against infection, resulting from a liver-produced protein deficit.
Risk Factors
- Tobacco smoking is the most significant risk factor, leading to a destruction of cilia.
- Genetic predisposition via alpha-1 antitrypsin deficiency increases risk.
- History of frequent respiratory infections in early childhood.
- Age over 65 years further elevates risk of developing COPD.
Signs and Symptoms
- Chronic bronchitis presents first with a productive cough persisting for three months over two consecutive years.
- Emphysema symptoms include quiet breathing and increased fatigue, often accompanied by weight loss and use of accessory muscles due to respiratory distress.
- Common symptoms include productive cough, rhonchi, wheezing, and shortness of breath, leading to air trapping and hyperinflation of the lungs.
