AUTOMATIC CARBON DIOXIDE ANGIOGRAPHY

• It is a device that enables the automatic delivery of carbon dioxide into the circulation with real-time pressure and volume control, using carbon dioxide as an effective and safe contrast agent. • Carbon dioxide angiography is an angiographic technique performed by administering a small amount of carbon dioxide into the circulatory system. • Carbon dioxide is an inert gas that dissolves in blood faster than oxygen and is easily eliminated from the body through respiration. • The viscosity of carbon dioxide is 400 times lower than that of other contrast agents, allowing visualization of microvessels that cannot be reached by conventional contrast media. • Due to its molecular structure, carbon dioxide can easily pass through total occlusions, enabling visualization of the distal segment beyond the lesion.
