Acid Base Disorders

Arterial blood gas analysis is used to determine the adequacy of oxygenation and ventilation, assess respiratory function and determine the acid–base balance.

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!

Anion Gap

OVERVIEW Anion Gap = Na+ – (Cl- + HCO3-) The Anion Gap (AG) is a derived variable primarily used for the evaluation of metabolic acidosis to determine the presence of unmeasured anions The normal anion gap depends on serum phosphate…
