- 38,000 pints: amount of donated blood used each day in the
United States.
- Someone needs blood every two seconds.
- About 1 in 5 people entering a hospital needs blood.
- Three: the number of lives saved by one pint of donated blood.

- A newborn baby has about one cup of blood in his body.
- 3.4 pints: the average red blood cell transfusion.
- Blood fights infection and helps heal wounds.
- Four main blood types: A, B, AB and O. AB positive is the universal
recipient,
O negative is the universal donor.
- Blood centers often run short of types
O and B blood.
- Shortages of all blood types happen during
the summer and winter holidays.
- If all blood donors gave 2 to 4 times a
year, it would help prevent blood shortages.

if you begin at age 17 and donate every 56
days until you reach
76 years
old.
- Three gallons of blood is used every
minute in the United States.
- Four steps to donate blood: medical history,
quick physical, donation and snacks.
- The actual blood donation usually takes
less than 10 minutes. The entire process --
from the
time you
sign in
to the time
you leave -- takes about an hour.
- Giving blood will not decrease your strength.
- You cannot get AIDS or any other infectious

- Much of today's medical care depends
on a steady supply of blood from healthy
donors.
- One unit of blood can be separated into
several components: red blood cells, white
blood cells,
plasma, platelets
and cryoprecipitate.
- Red blood cells carry oxygen to the body's
organs and tissue.
- One billion: the number of red blood
cells in two to three drops of blood.
- Red blood cells live about 120 days in
the circulatory system.
- Platelets support blood clotting and
give those with leukemia and other cancers
a chance
to live.
- Apheresis (ay-fur-ee-sis) is a special
kind of blood donation that allows a donor
to give
specific blood components,
such
as platelets.
- 42 days: the shelf life of donated red
blood cells.
- Five days: the shelf life of donated
platelets.
- One year: the shelf life of frozen plasma.
- Plasma is a pale yellow mixture of water,
proteins and salts.
- Plasma, which is 90 percent water,
constitutes 55 percent of blood volume.
- Healthy bone marrow makes a constant
supply of red cells, plasma and platelets.
- Car accident and blood loss victims
can need transfusions of 50 pints or more
of
red blood
cells.
- Bone marrow transplant patients need
platelet donations from about 120 people
and red blood
cells from about
20 people.
- Severe burn victims can need 20 units
of platelets during their treatment.
- Children being treated for cancer,
premature infants and children having heart

-- up to 4 pints
at a time.

donated blood in the days following the
September 11
attacks.
- Females receive 53 percent of blood
transfusions; males receive 47 percent.
- 94 percent of blood donors are registered
voters.
- 60 percent of the U.S. population is
eligible to donate blood -- only 5 percent
do.
- 17 percent of non-donors cite "never thought about it" as
the main reason for not giving, while 15 percent say they're too
busy. The #1 reason donors say they give is because they "want
to help others."
- After donating blood, you replace these
red blood cells within four weeks. It takes
eight
weeks to

donating.
- Granulocytes, a type of white blood
cell, roll along blood vessel walls in
search of
bacteria to eat.
