Answer.

Blood transfusion is the transfer of blood from one person (donor) to another person (recipient)through blood vessels. Transfusion is done to replace lost blood due to illness, accidents or bleeding. The following are the advantages of blood transfusion ;-

1. Blood transfusion does so much for patients in need. The gift of life is donated, tested, processedand sent to hospitals’ transfusion service departments where more important work is done toensure it is compatible with the recipient.

2. Blood transfusion has a number of advantages. These are some of the benefits the donated bloodcan provide for patients in need:

3. Increase low haemoglobin levels: low haemoglobin can cause damage to body organs andtissues due to low oxygen levels. Donated blood, with sufficient haemoglobin, can correct theproblem of low haemoglobin level of the recipient.

4. Help stop bleeding: bleeding may not be controlled if platelets and/or clotting factors arelow. Receiving blood with high clotting factors can solve the problem.

5. Keeps the heart pumping: low blood volume can lead to low pressure and the heart may notbe able maintain the circulation of blood.

6. Help with serious blood infections when other methods fail. For example, blood transfusionmay serve as a treatment method for people with sickle cell anaemia or blood cancer(leukaemia).

7. Provide red cells and platelets when the bone marrow is compromised as with blood cancers,bone marrow transplants, chemotherapy, etc.

8. Save someone’s life: people who have had a big loss of blood due to a number of reasons canhave their lives saved once they receive donated blood.

9. Because blood transfusion involves screening of the donor’s blood, if the donor has anyhealth problem it can be detected and hence treated before getting worse.
