 DESCRIPTION (provided by applicant): This is an innovative proposal to determine the capacity of molecular analysis of exhaled breath condensate filters (EBCF) to predict ventilator associated pneumonia (VAP) in trauma intensive care unit patients. Based upon preliminary data of 51 patients suspected of having VAP, who underwent bronchoalveolar lavage, we have previously demonstrated a strong correlation between bronchoalveolar lavage and breath condensate quantitative PCR. The goal of this proposal is to understand the changes that occur in the pulmonary microbial community of mechanically ventilated, critically injured adults to support the development of molecular analysis of EBCF to provide an earlier, more sensitive and specific diagnosis of VAP, to enable: 1) earlier recognition of a developing pneumonia, 2) targeted antimicrobial therapy, and 3) assessment of treatment response.

 描述（通过应用程序证明）：这是一个企业的项目，是呼出的冷凝水ERS（EBCF）分子分析的能力，以预测具有vap患者的创伤性肺炎（VAP）。我们以前已经证明了支气管化的灌洗与呼吸之间的相关性很强VAP的特定诊断：1）早期对发育中的肺炎的诊断，2）靶向抗菌治疗和3）评估治疗反应。
