Arterial CO₂ Tension in Metabolic Acidosis

Evaluation of the expected ventilatory response to metabolic acidosis in chronic hemodialysis patients

“…Hemodialysis population exhibits [10][11][12] a small reduction of [HCO 2 3 ] hence Winters' formulaobtained in severely ill children-does not run well. 15,16 The easy-to-use expression pCO 2 5 [HCO 2 3 ] 1 15 would be a reliable alternative formula-as we already suggested in a first small investigation 8 -being also suitable for the daily clinical practice.…”

“…Furthermore, for the first time in this population, we check also Fulop's rule-known as the 2-digit rule-according to which the expected pCO 2 value is equal to the 2-digit number to the right of the pH decimal point. 15,16…”
