Abg (Arterial Blood Gas) Test
An ABG test
measures how well your lungs bring oxygen into your blood and get rid of carbon dioxide. An ABG test also measures the acid-base (pH) balance in your blood. The results from the test are used to check if treatments, such as oxygen, are working. The amount of oxygen that you receive depends on your test results. The results also show imbalances in pH that can happen with kidney failure or heart disease. Your healthcare providers will use the results from this test, along with other tests and exams, to treat your conditions.
What to expect when ABGs are drawn:
The sample of blood is usually drawn from an artery in your wrist. Your healthcare provider will make sure you have good circulation in your wrist before drawing your blood. You will rest your wrist, palm up, on a small pillow or roll of gauze. Your healthcare provider will feel for your pulse, clean the area, then stick a needle into your artery. You may feel more discomfort when the needle is inserted because arteries are deeper than veins.
What to expect after ABGs are drawn:
Pressure will be firmly put on the site for at least 5 minutes, or until the bleeding stops. A pressure wrap will be placed on your wrist for at least an hour. Your will need to limit your activity as directed.
Seek care immediately if:
- The site begins to bleed again.
- You cannot move your wrist or fingers, and they are cold and pale.
- You develop a fever, or you develop redness at the site.
Contact your healthcare provider if:
- You have burning, numbness, or tingling in your hand.
- You have pain that is not relieved by treatment.
- You have questions or concerns about your condition or care.
Limit your activity as directed:
Ask your healthcare provider what activities you are able to do.
Follow up with your healthcare provider as directed:
You may need more tests or treatment. Write down your questions so you remember to ask them during your visits.
