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 ( = 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.
长期反复暴露于低强度爆炸超压是导致类似脑震荡后综合征持久后果的一个潜在原因。可穿戴式爆炸传感器工程师正在探索与这些后果相关的爆炸因素。然而，目前尚无能够真正记录个体所经历的所有爆炸的设备。对984名军人进行了关于其终身暴露情况和行为健康的调查。利用与重武器相关的目标结果，我们为每位参与者计算了一个广义爆炸暴露值（GBEV）。设定了200,000 GBEV单位的阈值，达到该阈值的参与者可能会报告更严重的症状。如果随着时间的推移，重复性低强度爆炸暴露即使产生细微影响，也可能对作战准备产生负面影响。暴露阈值可为如何减少有害暴露的决策提供依据。GBEV可用于跟踪持续暴露情况，并有可能识别出那些可能有发生与爆炸相关后果风险的人。
