INTRODUCTION
The nature of firefighters' work is characterized by its unexpected emergencies, sleep deprivation, night shift schedules, and smoke exposure during firefighting.
METHODS
Eighteen firefighters were involved in simulated live-fire activities. Firefighters' health status in terms of cardiovascular and mental conditions was checked by a physician and through reviewing their medical records. Firefighters' cognitive functions were evaluated by visual and auditory continuous performance tests (VCPT and ACPT) and paced visual and auditory serial addition tests (PVSAT and PASAT).
RESULTS
VCPT and ACPT scores were lower after the activity relative to baseline. The results revealed that ACPT appears to be more difficult than VCPT. Also, PVSAT and PASAT scores decreased significantly after the experiment. PASAT scores following firefighting tasks experienced a more significant decline compared to those of the PVSAT.
CONCLUSIONS
These findings suggest that firefighters have visual and auditory cognitive function problems following firefighting activities. In conclusion, auditory cognitive function was more influenced than the visual ability as a result of the experiment.
简介
消防员的工作性质具有突发性、睡眠剥夺、夜班工作安排和灭火时暴露于烟雾等特点。
方法
18 名消防员参与了模拟实火活动。医生通过检查消防员的健康状况和查看他们的医疗记录来检查消防员的心血管和精神状况。通过视觉和听觉连续性能测试（VCPT 和 ACPT）和 paced visual and auditory serial addition tests（PVSAT 和 PASAT）评估消防员的认知功能。
结果
与基线相比，活动后 VCPT 和 ACPT 分数较低。结果表明，ACPT 似乎比 VCPT 更难。此外，实验后 PVSAT 和 PASAT 分数明显下降。与 PVSAT 相比，消防任务后的 PASAT 分数下降更为显著。
结论
这些发现表明，消防员在进行消防活动后存在视觉和听觉认知功能问题。总之，由于实验的影响，听觉认知功能比视觉能力受到的影响更大。
