Although relatively safe, hypoxia exposure is a mandatory training requirement for aircrew that carries the risk of decompression sickness (DCS). Usually DCS affects only one individual at a time. Here, a cluster of three simultaneous cases is reported. Since these numbers were well in excess of the usually encountered incidence rate, the purpose of this work was to identify the most likely reasons using the epidemic DCS investigation framework which involves four main considerations: time; place; population; and environment. Based on time and place observations, this cluster clearly falls into the individual-based classification, where the environment is a primary concern. Indeed, equipment analysis allowed us to identify the most likely reason for two out of three cases (perforations in the oro-nasal oxygen masks worn during training). It led to replacement of damaged equipment and modification of teaching to prevent such damage. It is recommended that this investigative template may be used for any future occurrences of DCS in clusters.
虽然相对安全，但缺氧暴露是机组人员的强制性训练要求，有发生减压病 (DCS) 的风险。通常情况下，DCS 每次只会影响一个人。这里报告了三例同时发生的集群病例。由于这些数字大大超过了通常遇到的发病率，因此本工作的目的是使用流行的 DCS 调查框架确定最可能的原因，该框架涉及四个主要考虑因素：时间、地点、人群和环境。根据时间和地点的观察，这个集群显然属于个体分类，其中环境是主要关注点。实际上，设备分析使我们能够确定其中两例（在训练期间佩戴的口鼻吸氧面罩穿孔）的最可能原因。这导致更换了损坏的设备，并修改了教学内容以防止此类损坏。建议在今后的 DCS 集群发生时使用这种调查模板。
