  1. The fastest physiological mechanism for acid base correction is
    A) bicarbonate buffer system
    B) renal system
    C) respiratory system
    D) phosphate buffer system
    A) bicarbonate buffer system
    (this multiple choice question has been scrambled)
  2. pH
    • calculation of the presence of H
    • Test tip: Hydrogen (H+) -> Acid
  3. During aerobic metabolism cells primarily produce
    Adenosine triphosphate

  4. Bohr Effect
    • occurs as a result of CO2 binding to HgB causing decreased affinity of hemoglibin for oxygen
    • Test Tip: Bohr effect -> release of O2 -> tissue level
  5. Most definitive test for 'shock"
    • Elevated lactate
    • normal lactate is 0.7-2.1 mEq/L (remember Lactate 1-2)
    • Test tip: Shock -> Lactate
    • Lactate>4 ->significant
    • acidosis -> hyperkalemia
  6. Oxyhemoglobin dissociation curve Right shift:
    • HbG Releases O2
    • Right shift caused by; Raised temp; Raised 2-3 DPG; Raised acidosis; Reduced oxygenation
  7. Oxyhemoglobin dissociation curve Left shift
    • HgB hoLds O2
    • Left shift caused by: Low temp; Low 2-3 DPG; aLkalosis (Low acidosis); Lots of CO
  8. "Fixed acids" are removed by
    • Renal system only
    • Cannot be be changed by the bicarbonate buffer system
  9. Haldane effect
    is what emables us to remove large amounts of CO2
  10. Magority of CO2 is transported by
    bicarbonate in plasma
  11. The relationship of EtCO2 to PaCO2 should
    • demonstrate EtCO2 is slightly lower than PaCO2
    • this pressure gradient is what allows CO2 to be removed from lungs
  12. The relationship of pH, K+, EtCO2 and PaCO2
    • ^PaCO2 10mm Hg -> V pH 0.08 (for every change of PaCO2 10mmHg you will see a change of pH 0.08 in opposite direction)
    • ^ pH 0.1 -> V K+ 0.6 (for every change of pH 0.1 you will see a change of K+ 0.^ in opposite direction)
    • Change in EtCO2 is about = to change in PaCO2
