As blood passes through your lungs, oxygen moves into the blood while carbon dioxide moves out of the blood into the lungs. An ABG test uses blood drawn from an artery, where the oxygen and carbon dioxide levels can be measured before they enter body tissues. An ABG measures: 1  Partial pressure of oxygen (PaO2).
The capillaries near the alveoli contain blood low in oxygen and high in CO2. As the blood passes the alveoli gaseous exchange occurs. Oxygen from the alveoli diffuses into the blood in the capillaries and CO2 diffuses out of the blood into the alveoli then it is breathed out.
