Inhalational exposures are common among service members who deploy to southwest Asia. The objective of this study is to determine if deployed Air Force firefighters have any decline in spirometry related to deployment.
This study is a retrospective chart review.
The database search identified 302 firefighters with documentation of two separate spirometry examinations. For deployed firefighters, mean change in forced expiratory volume at 1 second (FEV1) percent predicted was -1.01 ± 7.86, forced vital capacity (FVC) was -0.46 ± 10.26 predicted, and mid-expiratory flow (FEF25-75) was -0.13 ± 12.97. For firefighters who had never deployed, mean change in FEV1 percent predicted was +0.08 ± 7.09, FVC was +0.72 ± 7.75, and FEF25-75 was -0.66 ± 16.17.
There does not appear to be evidence that deployment causes a significant change in lung function as measured by spirometry.
吸入性暴露在部署到西南亚的军人中很常见。本研究的目的是确定部署的空军消防员的肺活量测定法是否与部署相关的任何下降。
本研究是一项回顾性图表审查。
数据库搜索确定了302名消防员，他们有两次单独肺活量测定检查的记录。对于部署的消防员，预测的1秒用力呼气量（FEV1）百分比的平均变化为-1.01±7.86，用力肺活量（FVC）为-0.46±10.26预测值，呼气中期流量（FEF25-75）为-0.13±12.97。对于从未部署过的消防员，预测的FEV1百分比的平均变化为+0.08±7.09，FVC为+0.72±7.75，FEF25-75为-0.66±16.17。
似乎没有证据表明部署会导致肺活量测定法所测量的肺功能发生显著变化。
