An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide.An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle, [1] but sometimes the femoral artery in the groin or another site is used.
Radial artery puncture is a medical procedure performed to obtain a sample of arterial blood for gas analysis. [1] A needle is inserted into the radial artery and spontaneously fills with blood. The syringe is either prepacked with a small amount of heparin to prevent coagulation, or must be heparinised , by drawing up a small amount of heparin ...
A blood gas test or blood gas analysis tests blood to measure blood gas tension values and blood pH.It also measures the level and base excess of bicarbonate.The source of the blood is reflected in the name of each test; arterial blood gases come from arteries, venous blood gases come from veins and capillary blood gases come from capillaries.

The multiple inert gas elimination technique (MIGET) is a medical technique used mainly in pulmonology that involves measuring the concentrations of various infused, inert gases in mixed venous blood, arterial blood, and expired gas of a subject.
It is performed by measuring the arterial blood gases of the patient while they breathe room air, then re-measuring the blood gases after the patient has breathed 100% oxygen for 10 minutes. [1]:141 [2]:141 [3]
examination of arterial blood flow to the hands In medicine , Allen's test or the Allen test is a medical sign used in physical examination of arterial blood flow to the hands. It was named for Edgar Van Nuys Allen , who described the original version of the test in 1942.
Medical gas therapy is a treatment involving the administration of various gases. It has been used in medicine since the use of oxygen therapy. [1] Most of these gases are drugs, including oxygen. [2] Many other gases, collectively known as factitious airs, were explored for medicinal value in the late eighteenth century. In addition to oxygen ...
In addition to arterial blood gas, an anion gap can also differentiate between possible causes. The Henderson-Hasselbalch equation is useful for calculating blood pH, because blood is a buffer solution. In the clinical setting, this equation is usually used to calculate HCO 3 from measurements of pH and PaCO2 in arterial blood gases. The amount ...
