Medical technology has provided many life-saving discoveries but there is still no substitute for blood. In case of any medical emergency, the crucial element is the availability of blood. The blood donated would help a variety of individuals, surgery patients, trauma victims, cancer patients, thalassemia patients, premature babies and individuals with anaemia among others.
There is a constant requirement for regular blood supply as blood can be stored for a limited time only before its use. Regular blood donations by adequate number of healthy people are required to ensure that safe blood will always be available whenever and wherever it is required.
Blood is a precious gift which a person can give to another person — the precious gift of life. The decision to donate blood can always save a life, or even several lives, if the blood is separated into its particular components — the red cells, platelets and plasma — these can be used individually well for patients having specific conditions.
Who can donate blood?
Any healthy adult, both male and female, can donate blood. Men can donate blood once in every three months and women can donate every four months. The criteria that is universally considered for blood donor selection are:
- The person’s age should be between 18 to 65 years.
- The Haemoglobin count should not be less than 12.5g/dL.
- The Pulse rate should be between 50 and 100/minute with no irregularities in between.
- The Body Temperature should be Normal with oral temperature not exceeding 37.5 degree Celsius.
- The Body weight of the person should not be less than 45 kg.
How long will the body take to replenish the blood I donate?
The body will replace the blood volume (plasma) within 48 hours. It takes four to eight weeks to completely replace the red blood cells.
