Transcript of Artificial Blood

Why would blood substitutes work? Cons My Views My views cont. Analysis of sources Pros Pros for artificial blood:
1. Diseases that are transferred through blood transfusion, mainly HIV in regions of Africa, can be minimalised since artificial blood doesn't have any source of disease. (2)(8)

2. Since current donations are not matching increasing need for donations, this can allow everyone to get there blood donations.

3. Artificial blood can last on the shelves for up to 3 years, so in scenarios such as war, artificial can be used so that they can stored for longer without being unusable. (2)(3) The idea behind synthetic blood is creating a artificial substitute to real blood so that we can avoid things like diseases between blood transfusion and also the increasing amount of blood donations needed. Cons
1. Current blood substitutes can only replace parts of blood, currently it can only replace haemoglobin and not coagulation.

2. It is currently not financially feasible to use artificial blood on a commercial scale especially where it's most needed in places such as Nigeria. (8)

3. As it still is in testing stages, current haemoglobin based artificial blood has a higher rate of heart attacks then normal blood transfusion. (3)(8) Artificial Blood I think that artificial blood will be a viable option in the future for especially in countries that have high rates of disease transfer via blood transfusion, this would bring great benefits to these places and if we continue to put funding into research for a cheaper artificial blood then it looks very prosperous On the other hand, I think that in the future artificial blood will not make it extremely big on the commercial market where it's need most due to the fact that Africa has low socio economic and development status, leaving very little room for science and funding. The major sources I used were reliable because of the fact that they are all part of an organisation or a newspaper corporation such as rsc.org, the Australian, rci.rutgers.edu, the indian times and The Daily Beast. Stem Cells Currently in very early testing process, scientists are trying to recreate this from the embryonic stem cells of a human. (6)(7) By Robert Tang 10F Principle 1: The first principle behind this is that blood components can be recreated and carry out the same functionality, this leads to the two current models: Haemoglobin based and Perflurocarbons (1)(2) This is a model of Hemopure, the most promising blood substitute, using polymerised cow blood to recreate the haemoglobin in blood

Haemoglobin based artificial blood will be accepted into your bloodstream as it will be recognised as normal blood. Perflurcarbons will have to be transported in using other methods such as mixed with antibiotics and vitamins. No more diseases yay! More blood for me! Don't need to worry about expired blood anymore! Glossary:
Haemoglobin: The oxygen transportation device in red blood cells.
Coagulation: The process in which blood forms clots.
Transfusion: Receiving blood products into one's circulatory system.
Embryonic Stem Cell: Cells obtained from and embryo at a very early stage.
Antibiotics: A medicine that inhibits the growth or destroys microorganisms. Embryonic Stem cell
