WebInterpreting 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. WebThis is further complicated because blood is typically exposed to air bubbles at room temperatures (RT; 21-24 °C), but is analyzed in a closed system at 37 °C. Thus, for blood at pO2 150 mmHg (37 °C), exposure to air at 150 mmHg (RT) should increase the pO2 in blood to above 150 mmHg.
