Blood Gases Tests

Blood gas measurements are used to evaluate the oxygenation

and acid/base status. They are typically ordered if there is

worsening symptoms of an acid/base imbalance, difficulty

breathing, or shortness of breath. Blood gases may be ordered

along with other tests, such as electrolytes to determine if an

electrolyte imbalance is present, glucose to evaluate blood

sugar concentrations, and BUN and creatinine tests to evaluate

kidney function.




Blood gases, also known as: Arterial blood gases; ABGs;
pH; PO2; PCO2; Bicarbonate; HCO3.

? How is the sample collected for testing

Arterial blood is almost always used for blood gas analysis.

- The sample collect in syringe contains heparin.

- The sample must be in the ice, to prevent blood clotting.


Abnormal results of any of the blood gas components may

mean that the body is not getting enough oxygen, is not getting

rid of enough carbon

dioxide, or that there is a problem with kidney function.
