SPECIAL ARTICLE ON THE EVE OF BLOOD DONATION CAMP

THE GIFT OF BLOOD IS THE GIFT OF LIFE

Facts about blood needs

• Every year our nation requires about 4 crore units of blood, out of which only a meager 40 lakh units of blood are available.
• Every two seconds someone needs blood.
• More than 38,000 blood donations are needed every day.
• A total of 30 million blood components are transfused each year.
• The average red blood cell transfusion is approximately 3 pints.
• The blood type most often requested by hospitals is Type O.
• Sickle cell patients can require frequent blood transfusions throughout their lives.
• More than 1 million new people are diagnosed with cancer each year. Many of them will need blood, sometimes daily, during their chemotherapy treatment.
• A single car accident victim can require as many as 100 units of blood

Facts about the blood supply

• Type O-negative blood (red cells) can be transfused to patients of all blood types. It is always in great demand and often in short supply.
• Type AB-positive plasma can be transfused to patients of all other blood types. AB plasma is also usually in short supply.

Facts about the blood donation

• The average adult has about 10 units of blood in his body. Roughly 1 unit is given during a donation.
• A healthy donor may donate red blood cells every 56 days, or double red cells every 112 days.
• A healthy donor may donate platelets as few as 7 days apart, but a maximum of 24 times a year.
• Only 7 percent of people in India have O-negative blood type. O-negative blood type donors are universal donors as their blood can be given to people of all blood types.
• 0.4 percent of people have AB-blood type. AB-type blood donors are universal donors of plasma, which is often used in emergencies, for newborns and for patients requiring massive transfusions.
• All donated blood is tested for HIV, hepatitis B and C, syphilis and other infectious diseases before it can be transfused to patients.

 

Facts about blood and its components

• Blood makes up about 7 percent of your body's weight.
• There are four types of transfusable products that can be derived from blood: red cells, platelets, plasma and cryoprecipitate. Typically, two or three of these are produced from a unit of donated whole blood – hence each donation can help save up to three lives.
• Donors can give either whole blood or specific blood components only. The process of donating specific blood components – red cells, plasma or platelets – is called apheresis.
• One transfusion dose of platelets can be obtained through one apheresis donation of platelets or by combining the platelets derived from five whole blood donations.
• Donated platelets must be used within five days of collection.
• Healthy bone marrow makes a constant supply of red cells, plasma and platelets. The body will replenish the elements given during a blood donation – some in a matter of hours and others in a matter of weeks.
