Following the crash of Asiana flight 214 at SFO last weekend, blood banks around the area put out a call for donors -- and donors they got.
Because the community was so willing to give up their blood to help hospitals receiving victims of the crash, now blood banks are running on empty again.
Stanford's School of Medicine Blood Center says that it continues to urgently need type O-positive and O-negative blood and platelets (a small cell fragment that helps blood clot). Like Blood Centers of the Pacific, donations that it received following the crash allowed them to provide enough blood to Stanford Hospital and Lucile Packard Children's Hospital for the victims, but supplies are low again.
"We actually import blood from outside of the state," Lisa Block, spokeswoman for Blood Centers of the Pacific in San Francisco, said, adding that San Franciscans don't give as much blood as people in other areas.
And while everyone is asked to roll up their sleeve and give, it's O-negative blood types that are especially encouraged to donate since their blood is the only kind accepted by all other blood types.
"The first thing you do when someone comes in bleeding out, is you start pounding them with O-negative," Block said. "It's the O-negative that sustains them." "And," she added, "it is the only type used for newborn babies."
