  1. Hypoventilation causes (slow/shallow breathing)
    high CO2 because CO2 builds up because you're not blowing it off and combines with acid to make you acidic
  2. hyper ventilating (rapid/deep breaths)
    co2 becomes low because you are blowing off too much and you become alkolynic because you are blowing off too much acid
  3. acidonic ranges
    < 7.35
  4. alkolynic range
    > 7.45
  5. how to determine whether compensation is metabolic or respiratory if PH is normal
    check which side PH is closet to (acidic or alkolynic) and see rather HCO3 (base) or CO2 matches PH as far as being acidic or alkolynic which ever one matches your PH is your problem, which ever one doesn't is compensating.

    • ex. PH (7.45) CO2 (50) HCO3 (30)
    • answer is metabolic alkolysis fully compensated by respiratory
  6. how to determine whether compensation is metabolic or respiratory if PH is abnormal
    which ever value has the bigger deficit is the problem. which ever value has the lower deficit is the compensating factor
  7. how to know if disorder is compensated
    • if PH norm = full compensation (and arrows go in same direction)
    • if PH abnorm = partial compensation (and arrows go in same direction)

    • if one value is normal then no compensation
  8. signs and symptoms of Metabolic Acidosis
    • Kussmauls breathing
    • SOB on exertion
    • weakness
    • disorientation
    • acetone breath
    • hyperkalemia
  9. signs and symptoms of metabolic alkalosis
    • Depressed respirations
    • muscle hypertoncity
    • hyperactive reflexes
    • tetany
    • convulsions
    • disorientation
  10. Signs and symptoms of respiratory acidosis
    • weakness
    • giddiness
    • drowsiness
    • confusion
    • disorientation
    • coma
    • flushing
    • headache
    • increased heart rate
    • possible hypoxia
    • hyperkalemia
  11. S&S of resp alkalosis
    • hypocapnia
    • vasoconstriction
    • hyperventilation
    • high body temp
    • lightheadedness
    • circumoral parethesias
    • numbness and tingling
    • sweating
    • muscle irritability/cramps
    • tetany
    • convulsions
    • comas
    • HYPOkalemia
  12. things that can cause metabolic acidosis
    • uncontrolled diabetes
    • diarrhea
    • starvation
    • renal insuffiency
    • asprin intoxication (salicylate)
    • shock
    • and strenuous exercise
