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).
1 Respiration includes gas exchange in the lungs, circulation of gases through the blood stream, and transfer of gases at the cellular level. 2  Air is drawn into the air sacs of the lungs, where oxygen from the air can enter the blood. 3  Carbon dioxide exits from the blood into the alveolar air. Oxygen then diffuses into the cells, and carbon dioxide enters the blood. 2  The blood then circulates back to the lung, where the process begins again. 3  Definition of Ventilation Ventilation is the process of moving gases through the respiratory tract.
