Artificial tested on individuals in U.S.A, after patients

Artificial blood affects our society in various ways, one being affecting society socially as, oxygen carriers save lives of human beings by providing immensely oxygen rich blood for blood transfusions.

Scientists from the an experimental branch of U.S.A’s military commenced producing blood substitutes for employment in rural areas and to transfuse blood to wounded marines more quickly. The blood is composed  of the hematopoietic stem cells taken out from umbilical cord between the mother and fetus of humans. Each cord can yield roughly three blood transfusions. The blood is being made for the DARP Agency by Arteriocyte. The FDA has tested and approved the safety of this blood from already submitted O-negative blood. Using this, precise, oxygen carrier will diminish the costs per unit of blood from $5,000 to equal or less than $1,000. This undoubtedly is favourable to the economy of society.

Artificial blood has been at the focus of many controversies. Doctors discarded the use of HemAssist, the first oxygen carrier tested on individuals in U.S.A, after patients who received the artificial blood died more repeatedly than those who collected donated blood. Sometimes, medicinal associations have had difficulties proving that their oxygen carriers are effective. Part of this is because artificial blood is contrasting from real blood, so it can be complex and confusing to develop precise methods for comparison. In alternative situations, such as when artificial blood is used to deliver oxygen through swollen brain tissue, the outcome can be hard to gauge.

Another source of controversy has concerned artificial blood studies. Northfield Laboratories began testing an oxygen carrier called PolyHeme on trauma sufferers. The survey took place at more than 20 hospitals around the United States. Since myriads of trauma sufferers are unconscious and cannot provide consent for medicinal operations, the FDA passed the test as a no-consent study. In a nutshell, doctors could administer patients PolyHeme rather than actual blood without asking first. Due to these controversies, some people might see artificial blood as unethical.
