Obtaining the blood:
There are two main methods of obtaining
blood from a donor. The most frequent is
to simply take the blood from a vein as
whole blood. This blood is typically
separated into parts, usually red blood cells
and plasma, since most recipients need
only a specific component for transfusions.
A typical donation is 450 millilitres of
whole blood, though 500 millilitre
donations are also common.
The other method is to draw blood from
the donor, separate it using a centrifuge or
a filter, store the desired part, and return
the rest to the donor. This process is called
The blood is drawn from a large arm vein close to
the skin, usually the median cubital vein on the
inside of the elbow. The skin over the blood vessel is
cleaned with an antiseptic such as iodine or
chlorhexidine, to prevent skin bacteria from
contaminating the collected blood and also to
prevent infections where the needle pierced the
A large needle (16 to 17 gauge) is used to
minimize shearing forces that may physically
damage red blood cells as they flow through
the needle. A tourniquet is sometimes
wrapped around the upper arm to increase
the pressure of the blood in the arm veins
and speed up the process. The donor may
also be prompted to hold an object and
squeeze it repeatedly to increase the blood
flow through the vein.
