Abstract

Introduction: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.Methods:This study is a retrospective chart review.Results: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.Conclusion:There does not appear to be evidence that deployment causes a significant change in lung function as measured by spirometry.
