Blood Gas Interpretation
The blood gas is used to rapidly assess ventilatory function and identify acid-base disorders – and will also generally provide point-of-care testing of a number of values such as electrolytes, blood glucose and haemoglobin.

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: compensation
Franz Wiesbauer looks at acid-base compensation and some super-simple rules that will help you decide whether compensation is adequate or not.
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.

Acid base disorders and Osmolar Gaps
This is quick reference page to acid base disorders in toxicology and osmolar gaps. Zeff a toxicologist from Melbourne talks through his approach and the errors that can occur with osmolar and anion gaps.
Osmolar Gap
Osmolar Gap: Osmolar gap = Osmolality (measured) - Osmolarity (calculated): NOTE: is a pragmatic clinical aid - the units are different (osmolality =mOsm/kg and osmolarity = mOsm/L) so it doesn't make mathematical sense!
