What is artificial blood?
artificial blood is the basic filler for the human cardiovascular system used in some medical procedures or for the treatment of certain conditions. It is also known as blood replacement or blood replacement, and although it does not work as a full replacement for blood, it helps to take up space and carry some important gases. There are two main categories of artificial blood: oxygen therapeutics, for artificial blood that carries oxygen, and volume expanders for inert blood. Artificial blood solves this by acting as a volume expander that copes with the lost amount of blood. Because the real blood has considerable capacity to carry oxygen, if volume is detained, the dilute ratio of real blood to artificial blood may be sufficient to be alive. Even in the middle, the level of real blood, with artificial blood, the level of human oxygen may be approximately three neighborhoods of the standard. At the external limit, a person using volume expanders can get to only seventh conventional red blood.
The problem of creating a blood substitute that can effectively carry oxygen has been difficult, and there are currently two main methods to do artificial blood. The first uses perfluorocarbones to transport oxygen and release. Perfluorocarbones are mixed with a number of other things, including salts, nutrients, antibiotics and vitamins to create a composite as close to real blood. Perfluorocarbones can actually have certain advantages over real red blood cells, in the form of their small size, allowing them to travel through capillaries closed on red blood cells and help oxygenate tissues cut off. Artificial blood based on perfluorocarbon include fluosol-DA-20, PHER-O, Perftec and Oxycyte.
The second method uses hemoglobin derived from animals, humans or created with recombinant DNA technologies. Hemoglobin, although the natural component of red blood cells, can cause kidney toxicity when used in pure form so they must be nursingMen in many ways, including its encapsulation. There are a number of different artificial blood based on hemoglobin, including hemospane, oxyglobin, hemopure and polyhemu. Hemoglobin artificial blood is the type that is most persecuted by the US Army for field use, and so this area is now focusing on large investments and research.
