The acute respiratory distress syndrome (ARDS) is an acute inflammatory lung edema. The current definition includes three severity stages based on PaO2/FiO2 ratio measured at positive end-expiratory pressure (PEEP) of 5 cmH2O or more. ARDS was described for the first time by Ashbaugh et al. in 1967; it was suggested that PEEP could have beneficial effects. More than 50 years after its initial description ARDS is still of great concern for the intensivist because it accounts for 10% of ICU admissions and still supports a rough 40% mortality rate . Furthermore, ARDS can only be treated in the ICU environment because it very often requires invasive mechanical ventilation and because the mechanical ventilation settings can impact patient outcome. Indeed, the use of low tidal volume (VT) is strongly recommended as it has been demonstrated to decrease absolute mortality by 9% in the landmark ARMA randomized control trial (RCT). It is worth mentioning that this trial was innovative in many aspects, like the titration of VT according predicted (PBW), not measured, body weight, the monitoring of plateau pressure (Pplat), the adjustment of respiratory rate up to 35 breaths/minute, and a pragmatic way to set PEEP.
