Hi dear i have a problem with mixed acid base disorders, i wanna to find a criteria for diagnosis them, but in literature i cant find it. In our previous studies we have found this equation, but i dont know it is true or not: every 10 mmhg in co2 concentration leads to 0.08 increase in PH and every 10 decrease in HCO3 induced 0.15 decrease in PH. Please help me if it is possible. Regards, Tayeb
