美国的应急服务很少能够在事故现场提供关键的输血,致使许多地区缺乏输血服务。 Few U.S. emergency services can provide crucial blood transfusions at accident scenes, leaving many areas lacking.

紧急事件现场的输血可以拯救生命, 但只有大约1%的美国紧急救援机构有能力提供, 将许多地区变成“血沙漠”。 Blood transfusions at the scene of emergencies can save lives, but only about 1% of U.S. EMS agencies are equipped to provide them, turning many areas into "blood deserts." 迅速失血是可预防死亡的首要原因,在30分钟内进行血液治疗可大大提高存活率。 Rapid blood loss is a leading cause of preventable death, and administering blood within 30 minutes can greatly increase survival rates. 尽管有各种好处,但国家法律、资金和培训等障碍阻碍了医院前血液方案的广泛采用。 Despite the benefits, barriers like state laws, funding, and training hinder widespread adoption of pre-hospital blood programs.
