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.

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.
An embolism involves the occlusion of blood vessels by an embolus. [1] Arterial occlusion by an embolus is termed 'arterial embolism'. An embolus is an agent that blocks blood flow by physically obstructing blood vessels. [1] This includes gas bubbles, [18] fatty deposits, amniotic fluid, [19] blood clots, and foreign material. Arterial emboli ...
CTA can be used in the chest and abdomen to identify aneurysms in the aorta or other major blood vessels. These areas of weakened blood vessel walls that bulge out can life-threatening if they rupture. CTA is the test of choice when assessing aneurysm before and after endovascular stenting due to the ability to detect calcium within the wall. [3]
Unlike some biometric systems, blood vessel patterns are almost impossible to counterfeit because they are located beneath the skin's surface. Biometric systems based on fingerprints can be fooled with a dummy finger fitted with a copied fingerprint ; voice and facial characteristic-based systems can be fooled by recordings and high-resolution ...
Additionally, damage to blood vessels can occur at the site of puncture/injection, and anywhere along the vessel during passage of the catheter. If digital subtraction angiography is used instead, the risks are considerably reduced because the catheter does not need to be passed as far into the blood vessels; thus lessening the chances of ...
Netflix's highly anticipated boxing event between Mike Tyson and Jake Paul experienced multiple technical glitches, leading to investor concerns over the company's ability to broadcast live events.
The Seldinger technique, also known as Seldinger wire technique, is a medical procedure to obtain safe access to blood vessels and other hollow organs. It is named after Sven Ivar Seldinger (1921–1998), a Swedish radiologist who introduced the procedure in 1953.
