Caption Experts at the Center for Deployment-Related Lung Disease developed protocols to get to the root of the problem for veterans who are experiencing lingering respiratory symptoms after deployment in Iraq and Afghanistan. For many patients, standard lung function tests appear normal in veterans, in which case they have to look deeper, to the smallest airways in the lungs. To address that issue, pulmonologists at National Jewish Health implemented the use of a simple, non-invasive test called “lung clearance index,” which provides the same valuable information as a surgical lung biopsy.
