He shared about an upcoming blood drive at Landmark Church on Monday, June 18 from 2-8p. In order to donate, a person must be 17 years old (16 with parental consent), weigh at least 110 pounds and generally feel healthy and well.
They take a unit of red blood cells and break it into various blood components. Because of this, one gift of blood during a blood drive can help multiple people. Blood contains about 55% plasma, less than 1% white blood cells and almost 45% red blood cells. When a person donates they fill a bag which is then separated at Hoxworth in the following ways...
-Red cells (transport oxygen in the body) settle to the bottom,
-Plasma (a volume expander primarily needed by burn patients) rises to the top and can be stored for 1 year. Plasma is the liquid part of the blood, in which the red cells, white cells and platelets are suspended.
-Platelets are needed for blood to clot properly and can only be stored for 5 days
The separated products are used to made specialty products such as Cryoprecipitate which is made from frozen plasma and used in the treatment of von-Willebrand's disease and to replace fibrinogen.
The following are the percentages of the four main blood types within the general population.
O 45% A 40%
B 11% AB 4%
How will blood be used in certain instances?
-In severe auto accidents 50 units are typically used
-In heart surgery 6 units of blood and 6 units of platelets are typically used
-In organ transplants 40 units of blood, 30 units of platelets, 20 units of cryoprecipitate and 35 units of frozen plasma are typically used
It is very interesting to note that there is NO artificial blood and therefore blood donations are always greatly needed.
Next week we will hear from Raphaelle Schmitz who is our exchange student at Batavia High School.
