Metabolic Component Facts: Body will not overcompensate when it comes to acid/base balance so: pH midpoint is 7.4 If pH on report is < 7.4 = original problem was acidosis in nature If pH on report is > 7.4 = original problem was alkalosis in nature Examples: 1. pCO2 is High and pH is 7.37 = compensated Respiratory Acidosis because in spite of
