Question 16

what are the steps in acid/base interpretation?

Answer 16

2. Is the pH acidotic or alkalemic?
3. Could the entire blood gas be from increased or decreased PaCO₂?
4. If NO….Is there evedince of chronic respiratory disturbance or acute metabolic disturbance?
5. If an acute metabolic disturbence is present is it accompanied by appropriate respiratory changes?
6. Is there an anion gap? (if high = metabolic acidosis)
7. Are the clinical data consistent with proposed interpretation?
