Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* A breath collection apparatus for collection of volatile organic compounds in breath onto a sorbent trap and Tedlar bag, as well as for the collection of a separate sample of room air.
* Analysis of the volatile organic compounds in breath and room air by short acoustic wave/gas chromatography.
* Interpretation of the volatile organic compounds with a proprietary algorithm in order to predict the probability of lower respiratory tract colonization and infection.
This study will test the hypothesis that the investigators can identify the presence of Pseudomonas aeruginosa by sampling the "head space" above culture media of sputum provided by patients with cystic fibrosis. This study will test the additional hypothesis that the investigators can identify the presence of Pseudomonas aeruginosa by sampling exhaled breath from the patient providing the sputum.
