With a longer shelf life than human blood, some blood substitutes can be stored for one to three years without refrigeration. Artificial blood can be safely shelved outside hospitals and then rapidly administered to patients in emergency situations.

What is artificial blood called?
A blood substitute (also called artificial blood or blood surrogate) is a substance used to mimic and fulfill some functions of biological blood. ... The main categories of "oxygen-carrying" blood substitutes being pursued are hemoglobin-based oxygen carriers (HBOC) and perfluorocarbon-based oxygen carriers (PFBOC).
What characteristics would artificial blood need in order to function well in the body?
Hence, an ideal blood substitute should lack antigenicity and eliminate, or at least substantially reduce, the ability to transmit infections. In addition, it should be readily available, should have a long half-life, and should be capable of being stored at room temperature.
Why do we need artificial blood?
Blood substitutes are more robust than regular blood and can withstand more harsh environments such as not requiring refrigeration and can be used in the pre-hospital environment. Synthetic blood delivers oxygen to the body faster than real blood which can limit bodily injury, particularly during heart attack.
What are plasma substitutes?
Plasma substitutes are colloidal solutions that contain particles of such a molecular size that they stay in the intravascular space for a useful period of time.
What are the disadvantages of using artificial blood?
Immune reactions to the blood. Risk of infections. Donor blood must match the blood type of the recipient. Blood must be refrigerated, and has a shelf-life of 42 days, while artificial blood products in development can be freeze-dried and stored at room temperature for up to two years.
How are stem cells being used for making artificial blood?
Researchers have developed a line immortal stem cells that allow them to generate an unlimited supply of artificial red blood cells on demand. ... Each stem cell only makes around 50,000 red blood cells before it dies off, at which point the researchers need a new blood donation.
Can blood plasma be made in a lab?
Human blood is approximately 55% plasma, which contains water, salts, enzymes, antibodies, and other substances. ... Plasma is later broken down into different products that become pharmaceuticals, like immunoglobulin, many of which can't be made in a lab.
Does the human body have plasma?
Plasma is the largest part of your blood. It, makes up more than half (about 55%) of its overall content. When separated from the rest of the blood, plasma is a light yellow liquid. Plasma carries water, salts and enzymes.
What are the main types of blood substitutes?
The two major types of blood substitutes are volume expanders, which include solutions such as saline that are used to replace lost plasma volume, and oxygen therapeutics, which are agents designed to replace oxygen normally carried by hemoglobin in red blood cells.
Is there a blood substitute?
There is currently no substitute for human blood. Despite more than 70 years of research, scientists have been unable to develop an ideal blood substitute. For a blood substitute to work, it must be able to mimic the ability of red blood cells to carry oxygen.
Which of the following polysaccharide is used as plasma expander?
The artificial colloid hydroxyethyl starch (HES) is among the most frequently used plasma volume expanders in the medical field.
Can agar be used as plasma substitute?
The homopo lysacchar ide used for intravenous infusion as plasma substitute is Agar.
What is the difference between plasma and serum?
Serum is the liquid that remains after the blood has clotted. Plasma is the liquid that remains when clotting is prevented with the addition of an anticoagulant.
What do Jehovah Witnesses use instead of blood?
ICS and PCS are usually acceptable to Jehovah's Witnesses. Tranexamic acid (antifibrinolytic) is inexpensive, safe and reduces mortality in traumatic haemorrhage. It reduces bleeding and transfusion in many surgical procedures and may be effective in obstetric and gastrointestinal haemorrhage.
When was the first synthetic blood approved for human use?
Approved by the FDA in 1989, the product was made by the Japanese and was called Fluosol-DA-20.
