Which term is used to describe bicarbonate in ABG testing?

Explanation:
Bicarb is the term used for bicarbonate in ABG testing. Arterial blood gas reports typically include pH, PaCO2, and HCO3-, and clinicians commonly refer to HCO3- as bicarb. This reflects the metabolic component of acid-base balance, since bicarbonate acts as the blood’s buffering system and is regulated mainly by the kidneys. The other terms point to different measurements: CO2 on an ABG relates to the respiratory side (carbon dioxide in blood), O2 is the oxygen level, and pH measures overall acidity. So using the shorthand bicarb helps you identify the bicarbonate level and its role in metabolic aspects of acid-base status.
