Blood gases
Alternate Names : Arterial blood gas analysis, ABG
Risks
There is very little risk when the procedure is done correctly. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others. Other risks associated with this test may include:
- Bleeding at the puncture site
- Blood flow problems at puncture site (rare)
- Bruising at the puncture site
- Delayed bleeding at the puncture site
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
Special Considerations
Tell your health care provider if you notice bleeding, bruising, numbness, tingling, or discoloration at the puncture site. Also let your doctor know if you are taking any blood-thinning medications (anticoagulants) or aspirin.
