State-of-the-art equipment is used at the Rotary Blood
Bank to process blood.
The following diagrams explain
in simple terms how blood components are separated.
Blood is collected as whole blood. |
|
|
Blood can be stored as whole blood (with all of the plasma present) or, much
more commonly, as packed red blood cells in which about 70% of the plasma
has been removed. This is done by light centrifugation, as shown here. |
|
|
The platelet rich plasma can then be expressed off, leaving packed red blood
cells. |
|
|
The platelet rich plasma can be centrifuged heavily a second time to separate the platelet concentrate. |
|
|
The supernatant plasma can be expressed into a third bag and stored as
fresh frozen plasma. The remaining platelet concentrate is utilised as a
platelet pack. |
|
A single donation of whole blood supplies three separate components
(packed red blood cells, platelets, fresh frozen plasma) that can potentially
benefit
three different patients.
