HCO3: down <22

Question 6

Metabolic Alkalosis

Answer 6

pH: up (basic)
PaCO3:
HCO3: up >26

Question 7

Respiratory Acidosis

Answer 7

Hypoventilation (retaining too much CO2)

Treatment: Increase ventilatory rate

Question 8

Respiratroy Alkalosis

Answer 8

Hyperventilation (blowing off too much CO2)

Treatment: decrease ventilatory rate

Question 9

Metabolic Acidosis

Answer 9

Build up lactic acid - lactic acidosis, diabetic keto acidosis, renal failure, sepsis, toxic ingestion

Question 10

Metabolic Alkalosis

Answer 10

Rare, loss of hydrogen ions (vomiting or gastric suction) - consumption of large amounts of baking soda or antacids

Treatment: correct underlying condition
