at this time, we should thank the people who are sincere to who created the method of making blood, so that human life can be saved this artificial blood. artificial blood can be given to a person, regardless of blood type, so no checking time is needed to ensure that donor blood fits with a patient. Artificial blood can be produced in large quantities, when the blood supply is very small. the blood produced through this chemical process is completely free of bacteria and viruses.

however, despite more than two decades of research, artificial blood has not been perfect as a surrogate blood.

a second kind of blood substitute using a hemoglobin solution to transport oxygen. but the hemoglobin in this format is less efficient in carrying oxygen.
however, the development of surrogate blood has proved to be a benefit of life emergency surgery. for example, haemorrhage from internal injuries often leads to death, but surgery using surrogate blood has improved survival from 17 to 80 percent in the last year.
