World Blood Donors' Day
Monday, June 18, 2007
14th June was world Blood Donor's Day. I missed scribbling about the occasion. But my friend Rushal did not miss out. In his post about blood donation, he answers the most common doubts related to blood donation.
When we discuss about blood donation, the name "Friends to support" clicks immediately. The creator of this site Sharif seems to have worked really hard on the venture. He has collected lot of useful information about Blood and Blood Donation. Now he has adopted a dynamic site that makes it easy to arrange the donor records with help of database. But with the earlier static version, he must have faced many problems. Like everyday, he had to manually enter the records in the webpage. Also he had to manually maintain a record of the donors. But in spite of these problems, he kept the flow going and he didn't just stop at creating a website or arranging a few blood donation camps. He also went ahead to establish a toll free Blood Donation Helpline to answer queries about blood donation. If you are in Anshra Pradesh, do dial in 1051 or 0863-2351725. Also you can check out the Friends to Support website.
Btw, here is some of the useful information he shares in Blood Donation facts.
There are four main blood types: A, B, AB and O.
The gift of blood is the gift of life. There is no substitute for human blood.
Every year our nation requires about 4 Crore units of blood, out of which only a meager 5 Lakh units of blood are available.
One blood donation can save as many as three lives. One unit of blood can be separated into several components, including red blood cells, plasma and platelets. Red blood cells carry oxygen to the body's organs and tissue. Plasma is a pale yellow mixture of water, salts and proteins, including solvable clotting factors; plasma is 90 percent water and constitutes 55 percent of blood volume. Platelets are small blood cells that initiate blood clotting, controlling bleeding.
Every three seconds, someone needs blood. Blood fights against infection and helps heal wounds, keeping you healthy. Anemic patients need blood transfusions to increase their iron levels. Cancer, transplant and trauma patients and patients undergoing open-heart surgery require platelet transfusions to survive. People who have been in car accidents and suffered massive blood loss can need transfusions of 50 units or more of red blood cells.
The average bone marrow transplant requires 120 units of platelets and about 20 units of red blood cells. Severe burn victims can need 20 units of platelets during their treatment. Children being treated for cancer, premature infants, and children having heart surgery need blood and platelets from donors of all types.
Apheresis (ay-fur-ee-sis) is a special kind of blood donation that allows a donor to give specific blood components, such as platelets. Platelets must be used within five days of collection, hence blood donations are especially needed around 3-day weekends. Red blood cells must be used within 42 days. Plasma can be frozen and used for up to a year.
Blood makes up about 7 percent of your body's weight, and the average adult has 10 pints of blood in his or her body. Since a pint is pound, you lose a pound every time you donate blood.
