Acid-base imbalances Flashcards
Acid
Carbon dioxide
Carbonic acid
Base
Bicarbonate
Biphosphate
Carbonic acid-bicarbonate buffer system
Lungs and kidneys use acids and bases to regulate H+ concentration
Electrolyte exchange
Last resort
K+ exchanged for H+
Normal pH
7.35-7.45
Respiratory acidosis
Retention of CO2
Hypoventilation
Kidneys try to compensate by reabsorbing HCO3- and excreting H+
Respiratory alkalosis
Decreased CO2
Hyperventilation
Kidneys attempt to compensate by reabsorbing H+ and excreting HCO3-
Metabolic acidosis
Decrease in plasma HCO3
Hyperkalemia - H+ goes in cells, K+ gets kicked out
Kussmaul respirations - short and deep
Metabolic alkalosis
Increase in HCO3-
Kidneys reabsorb H+ and excrete HCO3-
Lungs breath slowly to retain CO3 which can cause hypoxemia
