You might think that donating blood
is most important during a natural disaster or other major event where many people
are injured. But hospitals everywhere always need donated blood. In fact, each year
blood transfusions help
save 4.5 million lives.
According to the American Red Cross, there's a 97% chance that someone you know
will need a blood transfusion at some point. One donation could save up to three lives.
And a single accident victim may need as many as 100 pints of blood.

Most people over the age of 17 can donate blood. In some states, you can donate

Things to Know on Your Donation Day
When donating blood, take these steps to make sure you stay safe and healthy:
Drink an extra 16 ounces of water or other nonalcoholic beverage before your appointment.
Eat a healthy meal, avoiding fatty foods like hamburgers, fries, or ice cream.
Wear a shirt with sleeves that you can roll up above your elbows.
Have somebody else drive you to and from the blood bank.
Have something to eat and drink after donating. Most blood banks will have snacks
for you when you've finished giving blood.
When you get to the blood bank, you'll answer a few questions about your medical
history. You'll also be asked about any recent travel, infections you may have, and
medicines you take. Your answers help the blood bank staff know if you are healthy
enough to give blood. Then they'll check your temperature, pulse, blood pressure,
and blood count.
What Happens During and After Donating Blood?
The actual donation part of giving blood usually takes about 10 minutes, and is
a lot like getting a blood test.
You will either be seated or lying down.
A technician will find a vein in your arm by tying a rubber tube around your upper
arm, and clean the skin over the vein with rubbing alcohol.
The tech will insert a needle into your vein. You may feel a small prick, kind
of like getting a shot.
Your blood will flow into a tube connected to the needle and into a bag, where
it's kept until it's needed.
You should tell the technician helping you if:
The sight of needles bothers you.
The sight of blood bothers you.
You feel nauseated or lightheaded.
This will help prevent a fainting spell, and keep you safe while you give blood.
After you donate, you may feel a little lightheaded or dizzy. These side effects
usually go away after a few minutes. Be sure to drink extra fluids during the 24 hours
after you donate. If you still feel unwell after that, call your doctor or have someone
else take you to the nearest emergency room.
The Food and Drug Administration (FDA) regulates blood banks in the United States.
They make sure that all needles and other equipment used for donating blood are sterile
and used only for one person, then thrown away. This ensures that nobody gets an infection
or disease from giving blood. Blood centers must also pass regular inspections by
the FDA to stay open.
