Quizplus · Accepted Answer

ABG (arterial blood gas) is the test that measures the levels of oxygen and carbon dioxide in the blood. CXR (chest x-ray) is used to visualize the structures in the chest such as the lungs and heart. PFT (pulmonary function test) measures lung function and can include spirometry, which assesses how much air a person can exhale, as well as other tests. MRI (magnetic resonance imaging) uses magnetic fields and radio waves to produce an image of the body and is not used to measure oxygen and carbon dioxide levels in the blood.
