Restrictive Lung Disease

• Facts:
  Interstitial lung disease
  Sarcoidosis
  Hypersensitivity Pneumonitis
  Pneumoconiosis
  Usual Interstitial PNA ( Idiopathic Pulmonary Fibrosis )
  Eosinophilic Pulmonary Syndromes
  
• Diagnosis:
  Decrease in both FEV1 and FVC, but FEV1/FVC is normal or increased
  
  
• Pneumonic:
  Etiology (PAIIINT)
  
  Pleural (fibrosis, effusions, empyema, pneumothorax )
  
  Alveolar (edema, hemorrhage, pus)
  
  Interstitial lung disease (idiopathic interstitial PNAs)
  Inflammatory ( sarcoidosis , COP )
  Idiopathic
  
  Neuromuscular (myasthenia,phrenic nerve palsy, myopathy)
  
  Thoracic wall ( kyphoscoliosis, obesity, ascites, pregnancy, ankylosing spondylitis )
  
• Notes:
  Characterized by loss of lung compliance
  Increased lung stiffness, decreased lung expansion
