The arterial blood gas analysis provides extensive and crucial information to the intensivist. It indicates the state of alveolar ventilation, the oxygenation, as well as the acid–base balance. It is an invaluable tool in expert hands. This review attempts to clarify the concepts related to respiratory and metabolic acid–base disturbances with several examples.
