P-Video: Rule of 15 in anion gap metabolic acidosis

By Michelle Lin, MD October 22, 2013 0 comments

Calculator

You have a patient with an anion gap of 30 and bicarbonate of 10 mEq/L. You also determine on VBG that the patient’s pCO2 is 25 mmHg. What trick of the trade can you use to quickly determine whether this low pCO2 is an appropriate compensation of the primary metabolic acidosis? Dr. Jeremy Faust and Dr. Corey Slovis explains the quick “Rule of 15”.
