Blood donation is a vital part of worldwide healthcare. It relates to blood
transfusion as a life-sustaining and life-saving procedure as well as a form of therapeutic phlebotomy as a
primary medical intervention. Over one hundred million units of blood are donated each year throughout the world.
Blood testing, donor eligibility and selection, adverse effects of donation, blood donation as a primary medical
intervention, and a brief discussion of pathogen reduction and inactivation for donated blood.
Indications
Blood donation for transfusion is a vital step in the management of many clinical problems, with the two
primary indications being anemia and acute blood loss. Blood donation itself is also used to primarily treat a small
subset of medical conditions. At the beginning of the 20th century, Karl Landsteiner identified ABO blood groups,
at which time blood typing of individuals was only beginning to be adopted as a universally standard practice.
Due to the inability to prevent blood from clotting once removed from the donor and thus store and transfer blood
to be delivered when needed later, transfusions were only carried out on a limited basis. Blood was transfused
directly from donor to recipient without intervening storage or transport. This method worked for small numbers of
patients and only on a small scale, as donors and recipients needed to be connected both in time and space. There
was a time when lists of donors were maintained of persons locally available to be called in to donate to patients
at any time as needed. Necessity drove the development of more flexible donation and storage practices when World
War I began. "On-demand" blood donation was not feasible for such a large scale effort. Soldiers were dying of other
wise non-fatal wounds due mainly to the inability to perform a timely blood transfusion.
Explanation
Blood donation is a very noble deed that has been done by many people from all walks of life. Many people may
think about it as a very simple task but that’s not always true. A blood transfusion requires a lot of skills
, which are required for a task to be done, in the most efficient and safe manner. Blood donation while an easy
task can be a very tough task in which one needs to be very careful while doing it.
Further Explanation
Blood donation, also known as blood banking, is when blood is taken, analyzed, and kept for transfusion for the benefit of another person.
In many nations, blood donors are compensated, while in others, donors give blood for the sake of charity. Although blood donation is safe, many donors experience dizziness.
Every year on June 14th, the global Donar Day is commemorated. People set a date for blood donation.
