Basic Concepts • Henderson-Hasselbach equation: [H + ]=24x(P CO / [HCO 3 - a 2 3] ) expressed in nEq/L • Normal pH=7.36-7.44 •P a CO 2 = 36-44 mm Hg • [HCO 3 ] - =22-26 26 mEq/L
Acid-Base Disorders • Metabolic Disorders are caused by a disturbance in [HCO 3 ] - . Metabolic Acidosis is present when [HCO 3 ] - is low and metabolic alkalosis is present when [HCO 3 ] - is high • Respiratory disorders d are caused dby changes in the P a CO 2. When the P a CO 2 is high, respiratory acidosis is said to be present, and when P a CO 2 is low, respiratory alkalosis is present.
