In many studies, a very good correlation has been shown between venous blood gas and the arterial blood gas. The first test that should come to mind in a deteriorating patient is an ABG (Arterial Blood Gas). The ability to accurately assess ABGs allows the perioperative nurse to assist surgical team members in restoring a patient's acid-base balance. The test results are used by medical professionals to assess how well oxygen is being distributed throughout the body and how well carbon dioxide is being removed. An Arterial Blood Gas, or ABG for short, is a test that measures the blood levels of oxygen (PaO2), carbon dioxide (PaCO2), and acid-base balance (pH) in the body. Print version /ABG.
