Setting the tidal volume is crucial when initiating invasive ventilation in ARDS patients because using too high a tidal volume can cause ventilator-induced lung injury (VILI). Keeping the tidal volume at 6 mL/kg of predicted body weight helps to minimize this risk. While positive end-expiratory pressure (PEEP), respiratory rate, and FiO2 are also important settings, they do not directly correlate with lung injury prevention as effectively as tidal volume management.
