Study Notes

Obstructive Pulmonary Diseases

The most common types of chronic lung diseases
Characterized by increased airflow resistance due to airway obstruction
Include asthma and COPD

Asthma

A chronic inflammatory disorder of the airways
Airway responsiveness depends on the degree of inflammation
Triggers of asthma attacks include:
- Allergens
- Exercise
- Respiratory infections
- Nose and sinus problems
- Medications and food additives
- Cold, dry air
- Stress
- Hormones
- Gastroesophageal reflux disease (GERD)
- Occupational exposure

Asthma: Pathophysiology

Hallmarks of asthma:
- Airway inflammation
- Airway hyper-responsiveness
Types of asthmatic responses:
- Early phase response
- Late phase response
Late phase response:
- More severe than the early-phase response
- Characterized by inflammation
- Inflammation involves eosinophils and neutrophils which infiltrate the airways

Asthma: Clinical Manifestations

Characteristic clinical manifestations of asthma include:
- Wheezing
- Cough
- Dyspnea
- Sensation of chest tightness
Asthma control and severity can range from mild to severe acute asthma and life-threatening asthma

Asthma Diagnosis

Diagnostic studies for asthma include:
- Symptoms
- Variable airflow obstruction
Asthma management approaches include:
- General management
- Acute asthma exacerbation

Asthma Medications

Relievers and controllers
Anti-inflammatory medications:
- Corticosteroids
- Antileukotrienes
Biological therapies:
- Anti-Immunoglobulin E therapy
Bronchodilators:
- β2-adrenergic agonists: Short-acting and long-acting
- Anticholinergic medications
- Methylxanthines

Chronic Obstructive Pulmonary Disease (COPD)

A respiratory disorder caused by smoking and characterized by:
- Persistent airflow limitation
- Enhanced chronic inflammatory response in the airways and lungs
Symptoms include:
- Dyspnea, difficulty breathing, or shortness of breath
- Limitations in activity
- Insidious onset and progressive nature
Previous COPD terminologies included:
- Chronic bronchitis
- Emphysema

COPD: Causes

Tobacco smoke
Occupational chemicals and dust
Infection
Heredity
Aging

COPD: Pathophysiology

Chronic inflammation in the:
- Airways
- Lung parenchyma (respiratory bronchioles and alveoli)
- Pulmonary blood vessels
Characteristics of COPD often include:
- Emphysema
- Chronic bronchitis
Processes contributing to COPD:
- Airflow limitation
- Air trapping
- Gas exchange abnormalities
- Mucus hypersecretion
- Pulmonary hypertension
- Systemic abnormalities

COPD: Classification

COPD classification based on severity, disability, and lung function impairment:
- Mild
- Moderate
- Severe
- Very severe

COPD: Complications

Cor pulmonale
Acute exacerbations of COPD
Acute respiratory failure
Depression and anxiety

Cor Pulmonale

Right ventricular hypertrophy or failure due to pulmonary hypertension
Results from long-term pulmonary hypertension caused by COPD
Manifestations include:
- Peripheral edema
- Jugular vein distention
- Hepatomegaly
- Right ventricular heave
- Tricuspid valve regurgitation
