About this trial
objective of LUNG-I3 study is to assess the quantitative and functional differences in cells between blood and bronchoalveolar lavage (BAL) fluid after an infection, with a special focus on alveolar macrophages and neutrophils

Primary outcomes
immune cells patterns in VAP
The primary endpoint will be to describe and compare the distribution of immune cells within the lung and the blood before VAP diagnosis (VAP prediction) and at the time of VAP diagnosis.
