NeoPlastic Effusion

Map Branches

• Loss Lung Volume
  • Cause incomplete expansion of air spaces
• Obstructive (Aka Resorption/Absorption) 2 ways
  • Aquired
    • Obstruction of airway (ALVEOLAR DUCT)
      • Due to Aspiration of Foreign Body
    • Leads to resorption into blood of O2 trapped in alveoli
      • Creates pressure differential (Vacuum)
    • Pressure in unobstructed area = higher
    • Pressure in Obstructed area causes Collapse
    • Less space in cavity with collapsed lung = Low Pressure
    • Higher pressure areas puts force on Mediastinum
      • Mediastinum shifts TOWARDS involved lung due to pressure
        • Moves from area of higher pressure to lower pressure
        • moves until pressure equalizes
        • Compresses ribs
          • Creates Scoliosis
    • Structures of Mediastinum
      • Heart
      • Aorta
      • Esophagus
      • Trachea
      • Thoracic Spine
  • Causes
    • (untitled branch)
      • Secretions or exudates within small bronchi
      • COPD = Chronic obstructive pulmonary disease
      • Bronchial asthma
      • Chronic Bronchitis
      • Bronchiectasis
      • Aspiration of foreign body
• Contraction
  • Local/Generalized Fibrotic changes in Lung/Pleura
  • Prevents full Expansion
  • Reduces Oxygenation
  • Predisposes to infection
• MicroAtelectasis (Aka Patchy)
  • Generalized loss of Lung Expansion
    • Due to Loss of Surfactant
    • Adult and neonatal respiratory disease
• Compression (Aka Passive Relaxation)
  • Compression of Lung Tissue
  • Accumulation of fluid in Pleura Cavity = PLEURISY
  • Fluid NOT compressible
  • Pressure of Fluid is higher then Lung
  • Higher pressure on involved lung
  • Mediastinum shifts AWAY from involved Lung (Opposite of normal)
  • Causes (T2 - NPR)
    • TB
    • Tumor
      • Obstructive or Compression Atelectasis
    • NeoPlastic Effusion
      • Cancer of Lung
    • Pneumothorax
      • 2 types
        • Traumatic Penetration
          • Open Wound to Parietal Pleural
        • Spontaneous
          • Penetration on inside
          • Causes (SLIT)
            • Lung Emphysema
            • Interstitial Lung Disease
            • TB = #2 cause of Death
      • Air in Pleural Cavity
    • Rt. Cardiac Failure
      • Blood to Pleural Cavity

	Kathleen Sundmark about 4 years ago	Great info. Lots of work. Thank you for these maps. They represent a lot of information and a great deal of work.

	Edward Shekhter about 4 years ago	Re: Great info. Lots of work. Thank you. Just got NovaMind about 3 weeks ago. This is my first go at it. There is so much information, but I am not sure if the way I presented/did this is the best way. Also I am looking for more insight and better way to do these mind maps, from experienced people.
