  1. In emphysema, what releases trypsin?
  2. What are three examples of COPDs?
    • 1) Emphysema
    • 2) Chronic Bronchitis
    • 3) Asthma
  3. What is the difference in partial pressure of O2 and CO2 in "Pink Puffers" and "Blue Bloaters"?
    • Pink Puffers: Low PaO2, normal PaCO2
    • Blue Bloaters: Low PaO2, High PaCO2
  4. What is the Transmural Pressure (Tp) in the lungs and airways in COPD patients?
    • Lungs: Positive Tp
    • Airway (alveoli): Negative Tp
  5. Why does Dynamic Compression occur in COPD patients?
    The transmural pressure becomes negative (Alveolar pressure less than arterial pressure)
  6. What are the three Restrictive diseases? What are they?
    • Fibrosis: Thickening of lungs
    • Sarcoidosis: ball of matter in lungs, inflammation, other organs involved
    • Scoliosis: curvature of spine
  7. What is the diff b/t dextroscoliosis and levoscoliosis?
    • Dextro: curvature of spine to right
    • Levo: curvature of spine to left
  8. In a flow-volume curve, is an increased lung volume effort-dependent/independent?
  9. In a flow-volume curve, is an decreased lung volume effort-dependent/independent?
  10. What happens to PERF, TLC and RV in the flow-volume curve in restrictive diseases?
    • PERF: decreases
    • TLC: moves right (Less VC)
    • RV: moves right (Less RV)
  11. What happens to PERF, TLC and RV in the flow-volume curve in COPD diseases?
    • PERF: Decreases
    • TLC: moves left (increased compliance)
    • RV: moves left (increased volume)
    • ***there is a scoop on the independent limb
  12. What is the main problem of CF patients?
    Persistent lung infections (>95% die this way)
