Study Shows Impaired Lung Function in First Responders
Bad news here.
The study by the Mount Sinai Medical Center's medical monitoring program examined more than 3,000 responders between 2004 and 2007, repeating exams conducted between the middle of 2002 and 2004.
Slightly more than 24 percent of the patients had abnormal lung function, the study found. In the earlier examinations, about 28 percent of the patients had similar results.
The article does not make it clear if this indicates a net improvement from the earlier examination; it appears from this that may be true:
The researchers tracked 3,160 people who took followup exams between September 2004 and December 2007; all had previous exams at least 18 months earlier.
