The only blood collected locally that directly benefited attack victims was 1,000 units sent to Baltimore on Sept. 11 to help victims of the Pentagon attack.
After the shipment was sent, officials determined there was not enough blood left over to meet the needs of area hospitals. Blood drives in the area since Sept. 11 have worked to replenish reserves so regional hospitals secure the blood needed to treat patients.
Local Red Cross officials say several blood drives held on campus in recent weeks have surpassed their expectations.
"We were able to quickly replenish the supply," said Lisa Whitaker, donor recruitment manager at the Orange County Red Cross. "Over the past two weeks, we have collected twice as much as needed."
During Monday's blood drive at the School for Public Health, the goal was to collect 50 blood units, said Casey Copp, director of blood services at the Orange County Red Cross. She said 70 people showed up to donate, and 61 productive units of blood were collected.
"We depend heavily on the campus throughout the year," Copp said.
Since the attacks, campus blood drives have averaged a turnout of 40 to 45 people, while in the past turnout would be no more than about 30. The main issue now, Copp said, is ensuring that blood donations do not decline.
"We're getting a better response now and want to maintain that," she said. Whitaker said 1,500 units of blood must be collected daily to serve regional needs.
Blood is good for 42 days after collection, but donors may only donate blood every 56 days, which creates the possibility of a shortage for about two weeks because so many people gave blood immediately after the attacks.
