Clinical Trial Summary

To determine if the analysis of exhaled breath condensate correlates with the development & resolution of pneumonia.

Description:

This proposal investigates the utility of exhaled breath condensate fluid (EBCF) collected from heat moisture exchange (HME) filters connected to patient's endotracheal tubes for early, non-invasive detection of ventilator-associated pneumonia (VAP) in critically ill or injured ICU patients. The development of pneumonia during mechanical ventilation is the most common healthcare-associated infection in severely injured patients, accounting for substantial morbidity, excess ICU and hospital stay, additional cost and increased mortality.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The number of patients with a positive association between the exhaled breath condensate fluid and BAL fluid in in patients suspected of pneumonia.	To determine the association between the microbial community in both EBCF specimens and bronchoalveolar lavage fluid (BALF) samples in critically ill and injured, mechanically ventilated patients suspected of VAP.	enrollment to hospital day 15
Primary	The per cent of positive correlation for the development & resolution of pneumonia based on changes in bacteria found in the exhaled breath condensate.	To develop a robust predictive model for the development of VAP and its resolution based on changes in the microbial community in EBCF collected over the course of ventilation.	enrollment to hospital day 15
