  1. Drugs that can cause asthma exacerbation (5 of them)
    • 1- aspirin
    • 2- NSAIDs
    • 3- B blockers
    • 4- Benzalkonium Cl
    • 5 - Sulfite preservatives
  2. Tidal Volume (what is it and how much)
    • normal breathing
    • 500mL
  3. Inspiratory reserve volume (IRV)
    (what is it and how much)
    • max amt of air that can be inspired above TV
    • max contraction of inspiratory muscles
    • 2100-3200mL
  4. Expiratory reserve volume (ERV)
    (what is it and how much)
    • extra amt of volume that can be expired after TV.
    • about 100mL (600 when combined with TV)
  5. Residual Volume (RV)
    (what is it and how much)
    • vol of air remaining after max expiration.
    • 1200mL
  6. Ispiratory Capacity(IC)
    • max volume that can be inspired after TV
    • TV+IRV=IC (approx 3500)
  7. Functional residual capacity(FRC)
    • vol in lungs after TV
    • ERV+RV=FRC
  8. Forced Vital Capacity (FVC, VC)
    • max vol of air that can be moved out during a single breath following max inspiration
    • IRV+TV+ERV=VC
  9. Total lung capacity(TLC)
    • max air in lungs
    • VC+RV=TLC
  10. alveolar ventilation rate (AVR)
    vol of air exchanged betw the atmosphere and the alveoli per min

    AVR(ml/min) = fq (breaths/min) x (TV-dead space)(ml/breath)
  11. Inhaled Corticosteroids (6)
    • Beclomethasone (QVAR)
    • Budesonide (Pulmicort)
    • Ciclesonide (Alvesco)
    • Flunisolide (Aerobid)
    • Fluticasone (Flovent)
    • Mometasone (asmanex twisthaler)
  12. systemic corticosteroids (3)
    • Methylprednisolone (medrol)
    • Prednisolone (millipred)
    • Prednisone (deltasone)
  13. Short acting B agonists (3)
    • albuterol
    • levabuterol
    • Pirbuterol
  14. long-acting B2 agonists (3)
    • arformoterol
    • formoterol
    • salmeterol
  15. Anticholinergics
    • ipratropiom
    • tiotropium
  16. Leukotriene Modifiers
    CysLT1 receptor antagonists
    • montelukast
    • zarfirlikast
  17. leukotriene modifiers
    5-LOZ inhibitors
    zileuton
  18. mast cell stabilizers
    cromolyn
  19. methyxanthines
    theophylline
