This Concept Map, created with IHMC CmapTools, has information related to: Sodium Bicarbonate, Bicarbonate (HCO3-) which acts as a buffer against Excess hydrogen ion concentration, Carbonic anhydrase converted into Water, Carbonic acid (H2CO3) catalysed by Carbonic anhydrase, 1 mmol/Eq per kg IV - slowly over 10 minutes then as guided by arterial blood gases must be accompanied by Adequate ventilation and CPR, Kidneys excreted 1% in the urine, Lungs exhaled as Carbon dioxide, Carbonic anhydrase converted into Carbon dioxide, Metabolic acidosis by converting to Carbonic acid (H2CO3), Kidneys reabsorbed into extracellular fluid, Water metabolised by Kidneys, SODIUM BICARBONATE indications Metabolic acidosis, Carbonic anhydrase reversing potential cardiac arrest, 1 mmol/Eq per kg IV - slowly over 10 minutes then as guided by arterial blood gases dissociates in water to form Bicarbonate (HCO3-), Carbonic anhydrase increasing pH, Water metabolised by Lungs, Carbon dioxide metabolised by Lungs, Prolonged cardia arrest > than 15 minutes administer 1 mmol/Eq per kg IV - slowly over 10 minutes then as guided by arterial blood gases, Excess hydrogen ion concentration reversing Metabolic acidosis, SODIUM BICARBONATE indications Phenobarbitone and tricyclic overdose, Metabolic acidosis administer 1 mmol/Eq per kg IV - slowly over 10 minutes then as guided by arterial blood gases
