  2. 2. DR.VINAMRA DHARIWAL MDS
  3. 3. BLOOD Facts• Blood flows everywhere through the human body.• We cannot live without it.• The heart pumps blood to all our body cells, supplying them with oxygen and food.• Blood also carries proteins and cell fragments called platelets that let blood clot where there has been an injury. DR.VINAMRA DHARIWAL MDS
  4. 4. What makes up our blood?• RED BLOOD CELLS (Erythrocytes) – The most abundant cells in our blood; they are produced in the bone marrow and contain a protein called hemoglobin that carries oxygen to our cells.• WHITE BLOOD CELLS (Leukocytes) – They are part of the immune system and destroy infectious agents called pathogens.• PLASMA – This is the yellowish liquid portion of blood that contains electrolytes, nutrients and vitamins, hormones, clotting factors, and proteins such as antibodies to fight infection.• PLATELETS (Thrombocytes) – The clotting factors that are carried in the plasma; they clot together in a process called coagulation to seal a wound and prevent a loss of blood. DR.VINAMRA DHARIWAL MDS
  5. 5. Blood FactsThe average adult has about FIVE liters of blood inside oftheir body, which makes up 7-8% of their body weight.Blood is living tissue that carries oxygen and nutrients toall parts of the body, and carries carbon dioxide and otherwaste products back to the lungs, kidneys and liver fordisposal. It also fights against infection and helps healwounds, so we can stay healthy.There are about one billion red blood cells in two to threedrops of blood. For every 600 red blood cells, there areabout 40 platelets and one white cell. DR.VINAMRA DHARIWAL MDS http://www.bloodbankofalaska.org/about_blood/index.html
  6. 6. Genetics of Blood Types• Your blood type is established before you are BORN, by specific GENES inherited from your parents.• You inherit one gene from your MOTHER and one from your FATHER.• These genes determine your blood type by causing proteins called AGGLUTINOGENS to exist on the surface of all of your red blood cells. DR.VINAMRA DHARIWAL MDS
  7. 7. What are blood types? Blood TypesThere are 3 alleles or genes for bloodtype: A, B, & O. Since we have 2 genes, AA or AO =there are 6 possible combinations. Type A BB or BO = Type B OO = Type O AB = Type AB http://learn.genetics.utah.edu/units/basics/blood/types.cfm DR.VINAMRA DHARIWAL MDS
  8. 8. How common is your blood type? 46.1% 38.8% 11.1% 3.9% DR.VINAMRA DHARIWAL MDS
  9. 9. Rh Factors• Scientists sometimes study Rhesus monkeys to learn more about the human anatomy because there are certain similarities between the two species. While studying Rhesus monkeys, a certain blood protein was discovered. This protein is also present in the blood of some people. Other people, however, do not have the protein.• The presence of the protein, or lack of it, is referred to as the Rh (for Rhesus) factor. A+ A-• If your blood does contain the protein, your blood is said to be Rh positive (Rh+). If your B+ B- blood does not contain the protein, your blood AB+ AB- is said to be Rh negative (Rh-). O+ O- http://www.fi.edu/biosci/blood/rh.html DR.VINAMRA DHARIWAL MDS
  10. 10. Did You Know? 450ml of blood can save as many as three lives. Every two seconds, someone in India needs blood. One out of every three of us will need blood in our life time. Even with all of today’s technology, there is no substitute for blood.

  11. 11. Blood TransfusionsA blood transfusion is a procedure in which blood is given to apatient through an intravenous (IV) line in one of the blood vessels.Blood transfusions are done to replace blood lost during surgery or aserious injury. A transfusion also may be done if a person’s bodycant make blood properly because of an illness. UniversalWho can give you blood? DonorPeople with TYPE O blood are calledUniversal Donors, because they can giveblood to any blood type.People with TYPE AB blood are calledUniversal Recipients, because they canreceive any blood type.Rh +  Can receive + or -Rh -  Can only receive - Universal DR.VINAMRA DHARIWAL MDS Recipient

  13. 13. Fact Sheet -1 Hospitals predict that the need for blood will increase 5% each year. Approximately only 5% of the eligible population in India donates blood. 75% of donors donate only ONCE per year.If they donated just two times per year there would never be any shortages. DR.VINAMRA DHARIWAL MDS
  14. 14. Fact sheet -2 A person has 5 litres of blood in their body. A person can donate blood every 90 days (3 months). Body recovers the Blood very quickly:  Blood plasma volume– within 24 - 48 hours  Red Blood Cells – in about 3 weeks  Platelets & White Blood Cells – within minutes DR.VINAMRA DHARIWAL MDS

  16. 16. Some Reasons to Donate Blood Blood is always needed for,  accident victims  cancer patients  blood disorder patients  surgery patients  Pre-mature, pre term babies  and many others……. 1 of out 10 hospital patients needs a blood transfusion 4.5 million Indians lives are saved by blood transfusions each year DR.VINAMRA DHARIWAL MDS
  17. 17. • Safety of Blood Donor & Blood Recipient (patient) because “Safe Blood” gives life, “Unsafe blood” gives infections• To ensure “Blood Safety”, – Strict “Donor Screening” at the Camp – “Testing” of collected blood to WHO specified standards – Strict “cross-matching” of blood samples to ensure safe transfusion to patient DR.VINAMRA DHARIWAL MDS
