Consider donating: Red Cross faces dire blood shortage in US
Severe weather across many parts of the country has caused problems, but one effect you may not have heard about is on the nation’s blood supply. According to the American Red Cross, the nation’s blood supply is critically low. The organization reports that the weather has caused many blood drives to be canceled and made it harder for the Red Cross to move supplies around to meet needs.
Nearly 16 million blood components are transfused each year in the U.S., according to the Red Cross. Daily needs include 29,000 units of red blood cells, 5,000 units of platelets and 6,500 units of plasma.
People need a blood transfusion for many reasons. Some may need blood during surgery. Others depend on it after an accident or because they have a disease that requires blood components. There is no substitute for human blood. All transfusions use blood from a donor.
The four blood types —A,b,abando—are differentiated by specific proteins called antigens. And blood also is classified by the Rhesus, or Rh, factor — negative or positive. Ideally, transfusions are performed with donated blood that’s an exact match for type and Rh factor. For emergency transfusions, especially if the situation is life-threatening or the matching blood type is in short supply, Type O-negative blood has the lowest risk of causing serious reactions for most people who receive it.
Blood donation is a voluntary procedure that can help save lives. Several types of blood donation meet different medical needs. The most common type is whole blood donation. About a pint of whole blood is donated, and the blood is then separated into its components: red cells, plasma and platelets.
To be eligible to donate whole blood, plasma or platelets, you must be: In good health.
At least 16 or 17, depending on the law in your state. Some states allow minors to donate with a parent’s or guardian’s permission. There’s no legal upper age limit, but policies vary among donation centers. At least 110 pounds.
Able to pass the physical and health history assessments.
If you aren’t already a blood donor, consider becoming one. Your gift can mean the world to someone in need.
