Study Notes
Obstructive Pulmonary Diseases
- The most common chronic lung diseases include asthma and COPD.
- Obstructive pulmonary diseases are defined as those that increase airflow resistance due to airway obstruction or narrowing.
Asthma
- A chronic inflammatory disorder of the airways.
- Characterized by airway hyper-responsiveness.
- Triggers include allergens, exercise, respiratory infections, nasal and sinus problems, medications and food additives, cold, dry air, stress, hormones and menses, Gastroesophageal reflux disease (GERD), and occupational exposure.
Asthma Pathophysiology
- The hallmarks of asthma are airway inflammation and hyper-responsiveness.
- Two types of asthmatic responses occur: early phase and late phase.
- The early phase response is triggered by allergens, irritants, or cold air, and results in bronchoconstriction and increased mucus production.
- The late phase response is more severe and is characterized by sustained inflammation, infiltration of eosinophils and neutrophils into the airways, and increased airway hyperresponsiveness.
Asthma Clinical Manifestations
- The characteristic clinical manifestations of asthma are wheezing, cough, dyspnea, and a sensation of chest tightness after exposure to a precipitating factor or trigger.
Asthma Diagnosis
- Diagnosis is based on characteristic symptoms, variable airflow obstruction, and pulmonary function tests.
Asthma Treatment
- Interprofessional approach to management, including medication therapy and lifestyle modifications.
- Medications include relievers and controllers.
- Relievers include short-acting and long-acting β2-adrenergic agonists, anticholinergic medications, and methylxanthines.
- Controllers include corticosteroids, antileukotrienes, and biological therapies such as anti-immunoglobulin E therapy.
Chronic Obstructive Pulmonary Disease (COPD)
- A respiratory disorder primarily caused by smoking.
- Characterized by persistent airflow limitation, usually progressive, often associated with an enhanced chronic inflammatory response in the airways and lung due to noxious particles or gases.
- Symptoms include dyspnea, difficulty breathing, and shortness of breath, usually insidious in onset and progressive.
- Past definitions of COPD included chronic bronchitis and emphysema.
COPD Causes
- Tobacco smoke
- Occupational chemicals and dust
- Infections
- Heredity
- Aging
COPD Pathophysiology
- Chronic inflammation found in the airways, lung parenchyma, and pulmonary blood vessels.
- Often have characteristics of emphysema and chronic bronchitis.
- Airflow limitation, air trapping, gas exchange abnormalities, mucus hypersecretion, pulmonary hypertension, and systemic abnormalities are among the various disease processes that occur in COPD.
COPD Classification
- Classified based on severity, ranging from mild to very severe.
- Classification considers symptoms, disability, and impairment of lung function.
COPD Complications
- Cor pulmonale
- Acute exacerbations of COPD
- Acute respiratory failure
- Depression and anxiety
Cor Pulmonale
- Right ventricular hypertrophy and dilation caused by pulmonary hypertension.
- A serious complication of COPD.
COPD Clinical Assessment
- History and physical exam.
- Pulmonary function tests.
- Chest imaging.
- Blood tests.
