Arterial Blood Gas Analysis for Respiratory Status

The lab analyst performs blood gas analysis to measure at least two of the listed parameters. The provider typically performs an arterial blood gas analysis, called an ABG, using arterial blood inserted into a blood gas analyzer that measures several parameters to assess respiratory status including pH, pCO2, pO2, CO2, HCO3, and calculated O2 saturation. These tests indicate the amount of oxygen and carbon dioxide as well as acid and base balance in the blood. Choose a location to see hospital-reported price summaries.
