Management of foreign body airway obstruction continues to be a major controversy in emergency medical care. Much of the disagreement is without doubt based on lack of a uniformly accepted model of acute airway obstruction representative of the clinical event. A variety of models have been used to assess different aspects of airway obstruction by foreign bodies. These models have analyzed, among other variables, kinetic energy and inertial and aerodynamic forces in attempts to focus on specific aspects of this controversy. Human volunteers, anesthetized and paralyzed patients, and cadavers have also been used. In several recent studies it was concluded that subdiaphragmatic pressure is the treatment of choice, while in at least one additional study firm back blows applied with the patient's head hanging downward were recommended as the treatment most likely to relieve airway obstruction. It seems likely that these apparently conflicting views can be reconciled and that a consensus recommendation for treatment of this emergency can be effected.
异物气道梗阻的处理在急诊医疗中仍然是一个主要的争议点。毫无疑问，许多分歧是基于缺乏一个被普遍接受的、代表临床事件的急性气道梗阻模型。各种模型已被用于评估异物气道梗阻的不同方面。这些模型除其他变量外，还分析了动能、惯性力和空气动力，试图聚焦于这一争议的具体方面。人体志愿者、麻醉和瘫痪患者以及尸体也被使用过。在最近的几项研究中得出结论，膈下压力是首选治疗方法，而在至少另一项研究中，建议在患者头部下垂时用力进行背部叩击，作为最有可能缓解气道梗阻的治疗方法。这些明显相互矛盾的观点似乎有可能得到调和，并且可以就这种紧急情况的治疗达成共识性建议。
