Which of the following is a treatment option for ARDS?

• A. 100% oxygen, CPAP, corticosteroids
• B. Low-flow oxygen only
• C. Antibiotics as sole therapy
• D. Inhaled bronchodilators

Answer: (A)

In ARDS the priority is to keep the lungs recruited and oxygenation adequate while minimizing further injury from ventilation. Providing support that keeps the alveoli open and maximizes oxygen delivery is key. Continuous positive airway pressure (CPAP) delivers a steady positive pressure that helps keep alveoli open at the end of each breath, reducing the shunt and improving gas exchange. Using a high fraction of inspired oxygen temporarily ensures enough oxygen reaches the blood as the lungs are severely impaired. Corticosteroids can help dampen the intense inflammatory response and reduce capillary leak, which may improve lung function when used appropriately in ARDS. So combining high oxygen delivery with CPAP support and anti-inflammatory therapy targets both oxygenation and the underlying inflammatory process, making it the best choice among the options. The other approaches don’t address the severe hypoxemia and diffuse alveolar damage as effectively: low-flow oxygen alone often isn’t enough, antibiotics alone don’t treat the lung injury itself unless an infection is driving it, and inhaled bronchodilators aren’t a primary ARDS treatment.
