Answer

The goals of mechanical ventilation in ARDS are to maintain oxygenation while avoiding oxygen toxicity and the complications of mechanical ventilation. Generally, this involves maintaining oxygen saturation in the range of 85-90%, with the aim of reducing the fraction of inspired oxygen (FiO2) to less than 65% within the first 24-48 hours. Achieving this aim almost always necessitates the use of moderate-to-high levels of positive end-expiratory pressure (PEEP).
