Pulmonary function (FEV₁ and FVC) among CF patients with Pneumococcus. Spirometery was compared from each patient at each time of Pneumococcal isolation with the values from two clinics immediately preceding and following this visit to assess for impact on lung function. No changes in FEV₁ were apparent at the time of pneumococcus infection compared to prior (p = 0.6665) or subsequent clinic visits (p = 0.4783). Furthermore, no differences in FVC were observed at time of pneumococcus colonization relative to prior values (p = 0.3354) or follow-up (p = 0.5385). Overall, there appeared to be no significant impact on lung function.
