Temple researchers are testing a new treatment that may give emphysema sufferers a better quality of life. Patients with emphysema have diseased lungs that overinflate because they don't expel air properly, according to Gerard Criner, chair of the Department of Medicine. Criner is testing a procedure that places metal coils around damaged portions of each lung, forcing the healthy part to work more efficiently. "We expect to see about a 25 percent improvement in their quality of life and a 12 percent improvement in lung function," he said.
