According to guidelines, which ventilatory strategy is recommended for ARDS to reduce mortality?

  1. Tidal volumes above 10 mL/kg predicted body weight
  2. Tidal volumes of 6 mL/kg PBW with plateau pressure under 30 cm H2O
  3. Zero positive end-expiratory pressure throughout ventilation
  4. Routine high-frequency oscillatory ventilation for every patient
Show answer and explanation

Correct answer: Tidal volumes of 6 mL/kg PBW with plateau pressure under 30 cm H2O

Evidence strongly supports low tidal volume ventilation (<6 mL/kg PBW) with plateau pressure <30 cm H₂O to reduce mortality in ARDS.
