AbstractInterpreting arterial blood gases (ABGs) is a common practice in intensive care units. The use of the temperature correction facility, however, is not standardized, and the effects of temperature correction on the ABG result may affect the overall management of the patient. The aim of this study was to discuss the significance of temperature correction. Current practice in the UK and Australia is discussed along with a review of physiological principles of oxygenation and acid-base balance. The alpha-stat and pH-stat methods of blood gas analysis are presented, with arguments for and against using the temperature correction facility for blood gas analysis. The study concludes with recommendations for practice.
