This is often performed on people with lung diseases, neuromuscular diseases, and other illnesses.
PaCO2 specifically evaluates carbon dioxide (CO2) levels in the blood.
These tests can help provide information about lung and kidney function and your body’s general metabolic state.

This article explains the purpose and risks of a PaCO2 test.
Every time you inhale, oxygen is brought into your lungs and delivered to thealveoli.
This is where the transfer of oxygen into and the removal of carbon dioxide from the blood occurs.
Neither is considered optimal.
When CO2 is elevated, it creates an acidic environment.
Risks and Contraindications
An ABG test is a standard blood draw usually taken from an artery.
Swelling and bruising can sometimes occur.
An artery will be selected for the draw.
As the needle is inserted, you may feel moderate pain.
The insertion tends to be more uncomfortable than when drawing blood from a vein.
However, some people only report a prick or some stinging.
You may have an infection or other complication.
Under 35 mmHg, and you have too little.
This can alter how well or poorly blood moves from thelungs to the capillaries and back.
