A 60-year-old adult with severe ARDS is intubated and receiving CMV. Ventilator settings on VC-AC (Volume Control / Assist-Control) and Arterial Blood Gas (ABG) analysis is provided below: Current ventilator settings (VC-AC): VT: 6 mL/kg IBW RR: 22/min FiO₂: 0.80 PEEP: +16 cm H₂O Plateau Pressure: 30 cm H₂O ABG: pH 7.29 PaCO₂ 52 mmHg PaO₂ 54 mmHg HCO₃⁻ 25 mEq/L The care team elects to transition the patient to APRV (Airway Pressure Release Ventilation) to improve oxygenation while maintaining lung-protective ventilation. Which initial APRV settings are most appropriate?
