Pulmonary function testing values included normal forced vital capacity (FVC) of 85.5\u2009\u00b1\u200915.5%; forced expiratory volume at 1 second (FEV1) of 81.4\u2009\u00b1\u200915.1%, FEV1\/FVC ratio of 0.79\u2009\u00b1\u20090.10, total lung capacity of 88.8\u2009\u00b1\u200920.3%, and diffusing capacity of 91.3\u2009\u00b1\u200915.4%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In the active duty military population identified with PE, evaluation should include lung function, chest and cardiac imaging, and exercise testing to determine if there are limitations to mandatory fitness requirements.
