Long-term, repeated exposure to low-intensity blast overpressure is a potential causal factor of lasting outcomes reminiscent of post-concussion syndrome. Wearable blast sensor engineers are exploring elements of blast that are associated with outcomes. Currently, however, there are no devices that can truly record all blasts experienced by an individual. Military service members (n = 984) were surveyed about their lifelong exposure and behavioral health. Using heavy-arms-associated target outcomes, we calculated a generalized blast exposure value (GBEV) for each participant. A threshold of 200,000 GBEV units was established at which a participant was likely to report more intense symptomology. If repetitive, low-intensity blast exposure has even a subtle effect over time, operational readiness could be negatively impacted. A threshold of exposure can inform decisions about how to reduce detrimental exposure. The GBEV can be used to track ongoing exposure and potentially identify those who may be at risk for developing blast-related outcomes.

从国防部范围内对军人的调查研究中开发爆炸暴露估计器

长期、反复暴露于低强度爆炸超压是导致脑震荡后综合征等持久结果的潜在原因。可穿戴式爆炸传感器工程师正在探索与结果相关的爆炸元素。然而，目前还没有能够真正记录个人经历的所有爆炸的设备。军人（n = 984) 进行了关于他们终身接触和行为健康的调查。使用与重型武器相关的目标结果，我们计算了每个参与者的广义爆炸暴露值 (GBEV)。建立了 200,000 GBEV 单位的阈值，参与者可能会报告更强烈的症状。如果随着时间的推移，重复、低强度的爆炸暴露甚至会产生微妙的影响，那么操作准备可能会受到负面影响。暴露阈值可以为有关如何减少有害暴露的决策提供信息。GBEV 可用于跟踪持续暴露，并潜在地识别那些可能有发展爆炸相关结果风险的人。
