Study Notes
Obstructive Pulmonary Diseases Overview
- Obstructive pulmonary diseases include bronchiectasis, cystic fibrosis (CF), asthma, and chronic obstructive pulmonary disease (COPD).
- Common characteristics: increased airway resistance due to obstruction or narrowing.
- Primarily affects functional ability, gas exchange, fatigue, infection, and self-management.
Learning Outcomes
- Understand the pathophysiology and management of conditions like asthma, bronchiectasis, cystic fibrosis, and COPD.
- Differentiate between acute asthma exacerbations and status asthmaticus.
- Recognize drug classes used in treating these respiratory disorders.
Key Terms
- α1-antitrypsin deficiency (AATD): A genetic condition that can lead to lung disease.
- Cor pulmonale: Right heart failure due to lung disease, often related to chronic hypoxia.
- Peak expiratory flow rate: A measure of how quickly air can be exhaled, important in asthma management.
Bronchiectasis
- Affects over 500,000 people in the US; more common in women.
- One in every 150 individuals over 75 is impacted.
- Characterized by permanent, abnormal dilation of medium-sized bronchi due to inflammatory changes.
- Results in a cycle of inflammation and airway damage, exacerbated by neutrophil accumulation.
- Microorganism colonization (e.g., Pseudomonas) weakens bronchial walls and forms infection pockets.
- Damaged mucociliary mechanisms lead to mucus stasis, decreased airflow, and impaired clearance from lungs.
- Around 40% of bronchiectasis cases have no known cause; in children, CF is the primary cause, while in adults, bacterial infections are most common.
Clinical Management
- Interprofessional care is essential for managing symptoms and improving quality of life in patients with obstructive pulmonary diseases.
- Emphasis on identifying etiology, clinical manifestations, and understanding the pathophysiology for effective treatment strategies.
