In plain words

What the trial is, and whether it could suit you

The overall aim is to compare the composition and spatial heterogeneity of the following in critically ill intensive care unit (ICU) patients: i) immune cell populations and their activation patterns, ii) the surrounding cytokine-chemokine milieu, including trans-compartmental fluxes of these mediators between the lung and bloodstream, and iii) the lung microbiome. Main hypotheses: * The immune cell population in bronchoalveolar lavage fluid (BALF) from patients with ARDS is dominated by neutrocytes, while T cells are depleted, and show evidence of hyper-activation and exhaustion * T cell hyper-activation and exhaustion is specifically compartmentalised to the lungs, and much more pronounced in moderate-to-severe than none-to-mild ARDS * Cyto- and chemokines derived from pulmonary immune cells are higher in moderate-to-severe than none-to-mild ARDS with a greater release from lungs to
