What is the arterial blood gases (ABGs) lab test?
An arterial blood gases (ABGs) lab test measures the amount of oxygen and carbon dioxide present in blood. This test is also used to determine the body’s acid-base level.
Why is the arterial blood gases (ABGs) lab test done?
An arterial blood gases (ABGs) lab test is done in order to:
- Monitor lung function,
- Monitor kidney function,
- Manage acutely ill patients,
- Diagnose a metabolic disease,
- Diagnose a head or neck injury that is causing difficulty in breathing.
What does an arterial blood gases (ABGs) lab test measure?
An arterial blood gases (ABGs) lab test measures the amount of oxygen and carbon dioxide present in the blood. This test also helps in identifying the body’s pH level.
Are there any risks associated with this test?
Pain and soreness at the site where the injection was inserted is common.
How should I prepare for this test?
No special preparations are needed for this test.
Can blood be drawn from a vein for this test?
Arterial blood is preferrable for this test, however, blood may be drawn from a vein incase of babies.
Can this test be performed in children?
This test can be performed in children when necessary.
What are the causes behind low oxygen saturation?
Low oxygen saturation is caused by diseases of the respiratory system.
Normal value of arterial blood pH is 7.38-7.42
Normal value of bicarbonate is 22-28 milliequivalents/L
Normal partial pressure of oxygen is 75-100 mm Hg
Normal partial pressure of carbon dioxide is 38-42 mm Hg
Normal oxygen saturation is 94-100 percent.
