Study Notes
Obstructive Lung Disease
- Alveoli: expand but deflate slowly, leading to increased lung volume and difficulty exhaling.
- Total Lung Volume: increased due to difficulty exhaling.
- Residual Volume: increased due to dead space where internal respiration doesn't occur.
- Inspiration: quick.
- Expiration: slow and prolonged, often 3-4 times longer than inspiration.
Restrictive Lung Disease
- Alveoli: deflate but cannot inflate fully, leading to decreased lung volume.
- Cause: scarring (fibrosis), parenchymal problems, stiffness in lungs, chest wall, muscles, or nerves.
- Lung Elasticity: decreased, impairing lung expansion.
Restrictive vs. Obstructive Lung Disease: Tests
- Forced Expiratory Volume (FEV1): significantly decreased in obstructive disease, moderately decreased in restrictive disease.
- Vital Capacity: slightly decreased or normal in obstructive disease, significantly decreased in restrictive disease.
Restrictive Lung Disease: Causes
-
Intrapulmonary: diseases of lung tissue
- Interstitial/Alveolar/Pulmonary Fibrosis: scarring of lung tissue, can be caused by COVID-19
- Atelectasis: collapse of a section of the lung
- Lung Resection: removal of a lung lobe, leading to reduced lung volume
- Interstitial Lung Disease: exposure to substances like asbestos, farmer’s lung, pneumoconiosis, sarcoidosis, and rheumatoid lung
-
Extrapulmonary: abnormalities outside the lung tissue
- Pleural Thickening: from pneumothorax or pleural effusion
- Abnormal Chest Wall: obesity (morbid obesity), ascites, pregnancy
- Spinal Deformities: scoliosis, kyphosis, lordosis
- Respiratory Muscle Weakness: neuromuscular diseases like Parkinson’s, Guillain Barre, ALS (Amyotrophic Lateral Sclerosis), MS (Multiple Sclerosis), cystic fibrosis, muscular dystrophy
Restrictive Lung Disease: Definition
- Physiological Characteristics: reduced total lung capacity, reduced vital capacity, reduced lung volume.
Restrictive Lung Disease: Signs & Symptoms
- Lung Compliance and Elasticity: damaged, leading to decreased expansion and deflation of the lungs.
- Decreased Vital Capacity: reduced amount of air that can be inhaled and exhaled.
- Decreased Tidal Volume: reduced amount of air breathed in and out during normal respiration.
- Decreased Total Lung Volume: due to restricted expansion or removal of lung tissue.
- Hypercapnia: high levels of carbon dioxide in the blood.
- Hypoxia: low levels of oxygen in the blood.
- Dyspnea on Exertion: shortness of breath during physical activity.
- Rapid Shallow Breathing: quick and shallow breaths.
- Decreased Activity Tolerance: fatigue with minimal exertion.
- Dry, Non-Productive Cough: dry cough without mucus production.
Restrictive Lung Disease: Treatment
-
Intrapulmonary Fibrosis: no cure, only symptom management
- Treatment: steroids, immunotherapy, oxygen therapy, and chemotherapy
- Extrapulmonary Obesity (Pickwickian Syndrome): progesterone, a respiratory stimulant
- General: treatment addresses the underlying cause, and symptoms are managed.
- Oxygen Therapy: CPAP (Continuous Positive Airway Pressure), BiPAP (Bilevel Positive Airway Pressure), mechanical ventilation for exacerbations.
- Conserve Energy: essential for patients with restrictive lung disease.
