Calculates ARDSnet lung-protective ventilation parameters for ARDS. Tidal volume: 6 mL/kg ideal body weight (IBW); may reduce to 4 mL/kg if needed. Plateau pressure goal: ≤30 cmH2O. Driving pressure (plateau − PEEP): target ≤15 cmH2O. Respiratory rate: 6–35/min to achieve pH 7.30–7.45. PEEP selected per high or low PEEP-FiO2 table. FiO2 goal: SpO2 88–95%.
