Medmastery: bicarbonate loss and acid overload
Franz Wiesbauer explains how to differentiate between metabolic acidaemia caused by a loss of bicarbonate and that caused by the addition of acid.

Medmastery: acid-base disorders
Franz Wiesbauer explains the relationship between pH, HCO3 and pCO2 and a simple rule which will help you decide whether the primary problem is respiratory or metabolic in nature.

Normal Anion Gap Metabolic Acidosis
Normal Anion Gap Metabolic Acidosis (NAGMA). HCO3 loss and replaced with Cl- -> anion gap normal. if hyponatraemia is present the plasma [Cl-] may be normal despite the presence of a normal anion gap acidosis -> this could be considered a 'relative hyperchloraemia'.
Metabolic Acidosis
a metabolic acidosis is an abnormal primary process or condition leading to an increase in fixed acids in the blood -> resulting in a fall in arterial plasma bicarbonate
Metabolic Acidosis Evaluation
A metabolic acidosis is a process which, if uncorrected, would lead to an acidaemia. It is usually associated with a low bicarbonate concentration (or total CO2), but an acidosis may be masked by a co-existing metabolic alkalosis.
