Winter Formula:

Expected pCO2 =1.5(Bicarb)+8

Question 12

Anion Gap equation

Answer 12

10-14

Na-(Cl+HCO3)

Question 13

Normal AG in metabolic acidosis

Answer 13

Hyperchloremic normal anion gap met acidosis

Question 14

Resp Acidosis expected compensation

Expected change in pH

Answer 14

Acute: Expect rise 1mEq/L HCO3/rise 10mmHg PCO2
