Blood is withdrawn from a small artery and then analyzed by a special machine that records the amount of carbon dioxide (waste gas) and oxygen in the blood. This test can help determine whether or not one needs extra oxygen.
refers to the pressure of oxygen and/or carbon dioxide in arterial blood; abbreviated ABG. An 'ABG' test routinely measures pressures of both gases, along with the level of blood acidity.
a blood test that measures how well the body is using oxygen.
specimen of arterial blood that assesses oxygenation, ventilation, and acid-base status
(arterial stick): A sample of blood taken from an artery to measure its oxygen, carbon dioxide, and acid content.
A test in which blood taken from an artery is analyzed for amounts of carbon dioxide and oxygen.
A term used to describe the assessment of arterial blood gas levels of oxygen (Pa02) and carbon dioxide (PaC02)
A test in which blood is taken from an artery and used to determine the amounts of oxygen and carbon dioxide in the blood.
ABG. The sampling of the blood levels of oxygen and carbon dioxide within the arteries, as opposed to the levels of oxygen and carbon dioxide in venous blood. Typically, the acidity, or pH, of the blood is measured simultaneously in ABG sampling.
Blood test that determines how well a patient is breathing and how well the lungs are working by measuring the oxygen, carbon dioxide and pH of the blood.
A blood test used to determine how well the lungs are working to oxygenate the blood. A blood sample is taken from an artery, usually in the wrist. An ABG measures pH (acid/base balance), PaCO2 (carbon dioxide), PaO2 (oxygen), and SaO2 (the percentage of hemoglobin that is carrying oxygen).
Used to assess oxygenation, alveolar ventilation, acid base status, and carboxyhemoglobin levels.
a test performed on blood drawn from an artery that identifies the amount of oxygen and carbon dioxide in the blood.
This sample of blood is taken from an artery. It is used to measure the oxygen, carbon dioxide and acid levels in the blood.
the test measures the partial pressure of oxygen and carbon dioxide dissolved in the arterial blood.
Arterial blood gas measurement is a blood test that is performed to determine the concentration of oxygen, carbon dioxide and bicarbonate, as well as the p H, in the blood. Its main use is in pulmonology, as many lung diseases feature poor gas exchange, but it is also used in nephrology (kidney diseases) and electrolyte disturbances. As its name implies, the sample is taken from an artery, which is more uncomfortable and difficult than venepuncture.
