What is a primary component of management for ARDS in pregnancy?

• A. Non-cardiogenic pulmonary edema with supportive care including oxygenation and low tidal volume ventilation
• B. Immediate cesarean delivery to reduce maternal oxygen demand
• C. High tidal volume ventilation to rapidly correct oxygenation
• D. Avoid any fluid management to prevent edema

Answer: (A)

In ARDS, the main issue is non-cardiogenic pulmonary edema from injury to the alveolar–capillary barrier, so the focus is on supporting the lungs and oxygenation while minimizing further injury. The best management approach is lung-protective ventilation combined with measures to optimize oxygenation and avoid fluid overload that can worsen edema. That means using lower tidal volumes (about 6 mL/kg predicted body weight) with adequate PEEP to prevent alveolar collapse, along with careful fluid management to maintain perfusion without tipping into edema. Delivery of the baby is not the primary strategy to treat maternal ARDS and is not done just to reduce oxygen demand; it’s considered only for obstetric reasons or if maternal/fetal status dictates. Using high tidal volumes would irritate the injured lungs and worsen outcomes, and completely avoiding fluids is inappropriate because some fluid support is often needed to maintain maternal hemodynamics. The essence is supporting the mother’s lungs with protective ventilation and careful oxygenation, which best addresses the ARDS in pregnancy.
