    Transcript
    Hi! Today we're going to talk about blood and blood products. My name is Jill Beavers-Kirby.The objectives of blood transfusion are to increase circulating blood volume, increase the number of red blood cells, or RBCs, to maintain haemoglobin levels, and to provide selected cellular component such as platelets or clotting factors. First, we'll talk about the ABO system. This is the presence or absence of a specific antigen on the surface of the red blood cells to determine your blood type. If you have the presence of type A antigens, then you have blood type A. If you have the presence of type B antigens, then you have blood type B. If neither type A nor type B antigen is present, then you have blood type O. Another system used to classify blood products is the Rh system. The Rh factor is an inherited protein. If the Rh factor is present on your cells, then you have Rh-positive blood. So for example, the presence of an A antigen is noted, the presence of Rh factor is noted, so you have blood type A positive. If the Rh factor is not present, then you have Rh-negative. So for example, if if you have neither type A nor type B noted on your cells, and the Rh factor is negative, then you have blood type O negative. So, what are packed red blood cells? These are indicated for acute blood loss, and these are also given because there is less damage of fluid overload. First in red blood cells are prepared from red blood cells using glycerol for protection, and then these are frozen. The deglycerolization process removes the glycerol, the white blood cells, and the plasma. The frozen red blood cells are then thawed and they must be used within 24...
