Statistics
> One in 20 Americans will require a blood transfusion at some point in their
> lives.
> Each year approximately 8 million volunteer donors give about 14 million
> blood donations.
> About 12 million units of red blood cells and whole blood, 8 million platelet
> units and 3 million plasma units are transfused annually.
> More than 90 percent of transfusion complications have been attributed to
> the presence of leukocytes in allogeneic blood.
> Every three seconds someone needs blood. Blood and blood products are
> used to treat accident and burn victims, cancer patients and other patients
> undergoing surgeries and medical treatments.
> People older than 65 use 43 percent of all donated blood. The demand for
> blood will increase as the population ages.
> Approximately 40,000 units of blood are used each day in the United States.
> One unit of blood is roughly the equivalent of one pint. On average an adult
> has approximately seven to nine units of blood.
> Blood centers often run short of type O and B blood. Shortages of all types
> of blood occur during the summer and winter holidays.
> Red blood cells can be stored for up to 42 days.
> Platelets can be stored for only five days.
> Frozen plasma can be stored for as long as one year.
> Each year, approximately 14 million units of blood are donated by
> volunteers. These donations are processed into about 27 million blood
> components, which are transfused into approximately 4 million patients
> a year.
> Because blood donations often are separated into several “components”
> (red blood cells, plasma and platelets, for instance), one donation can help
> save three lives.
