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.
A blood gas test or blood gas analysis tests blood to measure blood gas tension values, it also measures blood pH, and 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.

A result of between 3–5 seconds is equivocal, whereas the radial artery will not be considered for grafting if the result is longer than 5 seconds. [ 3 ] The utility of the modified Allen's test is questionable, [ 4 ] and no direct correlation with reduced ischemic complications of radial artery cannulation have ever been proven.
Diseases such as peripheral vascular disease can also result in local hypoxia. Symptoms are worse when a limb is used, increasing the oxygen demand in the active muscles. Pain may also be felt as a result of increased hydrogen ions leading to a decrease in blood pH created as a result of anaerobic metabolism. [65]
When she arrived at the emergency room, staff ran a variety of tests, including a blood test that showed that she had troponin in her blood, which indicates someone had a heart attack, ...
Hypoxemia refers to the low level of oxygen in arterial blood. Tissue hypoxia refers to low levels of oxygen in the tissues of the body and the term hypoxia is a general term for low levels of oxygen. [2]
A McDonald's restaurant in New Zealand is inside a decommissioned plane. See inside it, plus photos of the other most unusual McDonald's in the world.
Using a sheet pan as Garten does results in a browned, caramelized exterior. While a loaf pan can certainly produce a tasty meatloaf, the mixture steams in the pan and there's nowhere for the ...
