  1. distinct form of acute respiratory failure resulting from diffuse pulmonary injury of various causes
    acute respiratory distress syndrome
  2. first description of ARDS appeared in
    1967
  3. originally termed "adult" resp distress syndrome, but changed to acute as it occurs in ___ as well
    children
  4. mortality rate of
    40-60%
  5. most common causes of ARDS
    sepsis

    highest mortality at 70%
  6. type of pulmonary edema seen in ARDS is termed
    non-cardiogenic
  7. pulm edema seen in ARDS pt is termed non-cardiogenic because it
    IS NOT caused by heart failure
  8. lung compliance inc/dec causing lungs to become stiff/more elastic
    decrease

    stiff
  9. increase in alveolar-capillary permeability causes
    decrease in surfactant causing alveolar collapse (atelectasis)
  10. hypoxemia that responds poorly to supplement oxygen administration is termed
    refractory hypoxemia
  11. treatment for ARDS is primarily supportive: (3)
    • treatment of precipitative problem
    • provide adequate tissue oxygenation
    • provide adequate nutritional support
  12. PCWP in ARDS will most likely be
    normal
  13. lung compliance changes in ARDS because of (2)
    • hyaline membrane formation
    • alveolar consolidation
  14. etiologic factors of ARDS (atleast 5)
    • sepsis - #1
    • thoracic trauma
    • multiple blood transfusions
    • aspiration and near drowning
    • severe pneumonia
    • smoke inhalation
    • drug-induced lung surgery
    • inhaled toxins
    • shock
    • extensive burns
  15. ARDS affects (3)
    • lung mechanics
    • gas exchange
