9. **Common obstructive lung diseases include:**
- Asthma
- COPD (chronic bronchitis and emphysema)
- Respiratory tract infections (acute bronchitis, pneumonia)
- Abscess formation
- Pulmonary vascular disease (pulmonary embolism)
- Pulmonary hypertension
- Cor pulmonale
- Malignancies of the respiratory tract
10. **Obstructive lung diseases are characterized by:**
- Obstruction to airflow during expiration
11. **What is a V/Q mismatch?**
- Imbalance between the air entering the alveoli and the perfusing blood, causing
hypoxemia
12. **Clinical manifestations of acute hypoxemia include:**
- Cyanosis, confusion, tachycardia, edema, decreased renal output
13. **Restrictive lung diseases are characterized by:**
, - Inability to expand the lungs during inspiration
- Lung tissue is “stiff” and volume is reduced
14. **Clinical manifestations of restrictive lung disease:**
- Dyspnea, tachypnea, decreased tidal volume
15. **What is tidal volume (TV)?**
- The volume of air moved in or out of the lungs with each respiratory cycle
16. **Common restrictive lung diseases include:**
- Aspiration
- Atelectasis
- Bronchiectasis
- Bronchiolitis
- Pulmonary fibrosis
- Pulmonary edema
- Pneumoconiosis
- Allergic alveolitis
- Interstitial lung disease (ILD)
- ARDS
17. **Diagnostic tests for lung conditions:**
- Laboratory: ABG, CBC, CMP, sediment rate, CRP
- Radiologic: Chest x-ray, CT, lung ventilation/perfusion scan
- PFTs: Spirometry, lung volume testing, diffusion capacity, peak flow
18. **Clinical management includes:**
