Table 1 Respiratory mechanics at start (H0) and after a 5-h (H5) of low tidal volume mechanical ventilation (MV) following a lipopolysaccharide (LPS) or vehicle (saline) aspiration in wild type (WT) and interleukin-6 knock-out (IL-6KO) mice, receiving either recombinant human interleukin-6 (rHuIL-6) or vehicle (saline)

From: Interleukin-6 displays lung anti-inflammatory properties and exerts protective hemodynamic effects in a double-hit murine acute lung injury

Abbreviations: Peak Pr peak inspiratory pressures, Cstat quasi-static compliance of the respiratory system (calculated using a pressure-volume curve), Cdyn dynamic compliance of the respiratory system (calculated using the single frequency forced oscillation technique), Edyn dynamic elastance of the respiratory system (calculated using the single frequency forced oscillation technique). Volume history standardization (VHS) consisted in two inflations to an airway pressure of 30 cmH2O. N = 8 to 10 animals per group
