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.

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.

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.
Young and Yellow
Fulminant hepatic failure is defined as the appearance of hepatic encephalopathy in a patient with acute deterioration of liver function with no previous history of liver disease.
