WebFeb 18, 2024 · pH. pH is a scale from 0-14 used to determine the acidity or alkalinity of a substance. A neutral pH is 7, which is the same pH as water. Normally, the blood has a pH between 7.35 and 7.45. A blood pH of less than 7.35 is considered acidic, and a blood pH of more than 7.45 is considered alkaline. Web•Excess production of acid or decreased excretion of acid The anion gap is a useful calculation in assessing metabolic acidosis. Anion gap = [Na+] – ([Cl-] + [HCO 3-]) Loss of buffer has no effect on anion gap. Accumulation of organic acid (e.g., lactic acid) causes an increase in anion gap. Normal anion gap: <15 mEq/L Increased anion gap:
