Artificial Blood

Artificial blood is the general name for blood substitutes that imitate the basic functions of blood, such as transporting oxygen, nutrients, vitamins and other essential components, as well as ensuring acid-base balance and removing metabolic products from the body.

Artificial blood is used in medicine to treat various diseases, such as anemia, hemophilia, cancer, organ transplantation and others. It can also be used as an alternative to donor blood in case of shortage or incompatibility.

One of the most common types of artificial blood is packed red blood cells, which contains a large number of red blood cells (RBCs). It is used to treat anemia caused by blood loss or insufficient production of red blood cells.

Another type of artificial blood is plasma, which is the liquid part of the blood containing proteins, clotting factors and other components. Plasma is used to replace blood volume during blood loss, as well as to treat certain diseases associated with bleeding disorders.

In addition, there are other types of artificial blood, such as albumin, immunoglobulins and growth factors, which are used to treat certain diseases and conditions.

It is important to note that artificial blood is not a complete replacement for blood, since it does not contain all the necessary components and cannot replace all the functions of blood. However, it can be very useful in treating many diseases and conditions, and its use can significantly improve the quality of life of patients.

Artificial blood The name “artificial blood” is sometimes mistakenly believed to be similar in meaning to whole or canned donor blood. However, these two medical substances have completely different characteristics, purposes and areas of application. Whole blood is an equivalent vital fluid for the body: it is pure human blood with a full set of components, located in the recipient’s vascular system. There are a number of conditions for its use: firstly, there must be a quick and easy restoration of the original volume; secondly, there is no other therapy and diseases of the blood or internal organs; thirdly, the concentration of all components in the body is quickly restored within physiological ranges. Obtaining whole blood from the human vascular bed, in addition, is still economically unprofitable. That is why the existence of blood donation and its components has not lost its relevance. Blood replacement fluids All different collections of artificial blood “substitutes” are created in order to mitigate the severity of the tissue incompatibility reaction (verteza reaction) and save the amount of whole donor blood. To a certain extent, blood-substituting fluid can perform the same functions in a damaged circulatory system as blood, which normally fills the arteries, veins and capillaries of the body. Unfortunately, no blood substitute can be an ideal replacement for human blood in terms of the mass of the substance, but it is able to provide vital activity to tissues that have good and potential capabilities (for example, bone marrow). These can be organic compounds in the form of saline solutions, compositions of various proteins (collagen, hemoglobin, plasma), lipid emulsions, polymer solutions, electrolyte solutions, plasma replacement agents (hemodilution solutions), etc. Artificial blood is dry plasmalysin, a drug to maintain function immune system, which is used to prevent transfusion syndrome.
