• If you lose more than 15-30% of your blood, pallor and weakness will result.

• If you lose more than 15-30% of your blood, pallor and weakness will result.
• More than 30% will result in shock and possibly death.

• If you lose more than 15-30% of your blood, pallor and weakness will result.
• More than 30% will result in shock and possibly death.• Whole blood transfusions are given to replace substantial
blood loss and treat severe anemia.

• If you lose more than 15-30% of your blood, pallor and weakness will result.
• More than 30% will result in shock and possibly death.• Whole blood transfusions are given to replace substantial
blood loss and treat severe anemia.• Blood is collected, an anti coagulant is added
to prevent clotting, and it is stored in a
refrigerator for up to 35 days at 4ºC.

• Must get the correct blood type because the
plasma membranes of red blood cells (RBC’s)
have genetically determined proteins or
antigens.

Red Blood Cells (RBC’s)• An antigen is protein that the body sees as foreign and the
immune system releases antibodies against them.

Red Blood Cells (RBC’s)• An antigen is protein that the body sees as foreign and the
immune system releases antibodies against them.• We can tolerate proteins for our blood type, but another type
is foreign and will be attacked by our immune system.

Red Blood Cells (RBC’s)• An antigen is protein that the body sees as foreign and the
immune system releases antibodies against them.• We can tolerate proteins for our blood type, but another type
is foreign and will be attacked by our immune system.• Causes agglutination, or clumping, which clogs small blood
vessels.

Agglutination
Antibodies are present in the plasma which will attack RBC’s with surface antigens that are not the same as the individual’s blood type.

ABO Blood Types• The A blood type is found in about 41% of the American
population.• Can receive blood from A and O
donors.

ABO Blood Types• The B blood type is found in about 10% of the American
population.• Can receive blood from B and O
donors.

ABO Blood Types• The AB blood type is found in about 4% of the American
population.• Can receive blood from A, B, AB,
and O donors.

ABO Blood Types• The O blood type is found in about 44% of the American
population.• Can receive blood from O donors.

Rh Factor• Rh+ 85% of the population• Rh- No antibodies are normally present. If an Rh-
individual receives RH+ blood, anti Rh+ antibodies will be produced.
• If individual receives a second Rh+ blood transfusion, antibodies will attack and rupture the Rh+ blood.
![Page 16: Blood Typing. If you lose more than 15-30% of your blood, pallor and weakness will result.](https://reader034.fdocuments.in/reader034/viewer/2022051417/5697bf861a28abf838c87da0/html5/thumbnails/16.jpg)
Important Rh Factor Problem• If an Rh- woman has an Rh+ baby, her immune system
will produce anti Rh+ antibodies after exposure to the fetal blood in the placental bloodstream.
• Mothers are treated with Rhogam during pregnancy and after delivery to prevent the formation of these antibodies.
• Without treatment, mother’s antibodies could kill baby and complicate future pregnancies.
