Cystic Fibrosis Mechanisms
- Autosomal Recessive
- CFTR Chromosome 7
- Cl- channel Defect
- Decreased Chloride Secretion
- Increased Na and Water Reabsorption
- Increased Na and Cl in Sweat
- Dehydration of Mucous Layers
Cystic Fibrosis Symptoms and Complications
- Recurrent Pulmonary Infections
- Chronic Bronchitis
- Nasal Polyps
- Pancreatic Insufficiency
- Intestinal Obstruction
- Malabsorption and Diarrhea
- Vitamin Deficiencies
- Chronic Hepatic Disease
- Infertility in Males
Cystic Fibrosis Diagnosis and Treatment
- Sweat Chloride Test > 60 mmol/L
- Meconium Ileus
- N-acetylcysteine
- Antibiotic Prophylaxis
- Pulmonary Maintenance
- Lung Transplant
- Vitamin Replacement
Obstructive Lung Disease
- Blocked Airflow
- Increased residual volume
- V/Q Mismatch
- Decreased forced vital capacity (FVC)
- Decreased FEV1/FVC ratio
- Asthma
- Bronchiectasis
- Chronic bronchitis
- Emphysema
Restrictive Lung Diseases
- Poor Breathing Mechanics
- Interstitial Lung Diseases
- Goodpasture's Syndrome
- Eosinophilic Granuloma
- Granulomatosis with Polyangiitis
- Sarcoidosis
- Pneumoconiosis
- Idiopathic Pulmonary Fibrosis
- Drug Toxicity
- Acute Respiratory Distress Syndrome (ARDS)
- Neonatal Respiratory Distress Syndrome
Restrictive vs. Obstructive Lung Diseases
- Restrictive Lung Disease
- Decreased Lung Volume
- FEV1/FVC Ratio Normal to Increased
- Obstructive Lung Disease
- Increased Lung Volume
- Decreased FEV1/FVC Ratio
