The correct answer focuses on the phases of a ventilatory strategy specifically tailored for patients with Acute Respiratory Distress Syndrome (ARDS). In managing ARDS, the principles of protective ventilation are paramount, which aim to minimize ventilator-induced lung injury. This is typically achieved through low tidal volumes, maintaining a target of around 4 to 8 ml/kg of predicted body weight, which helps to prevent overdistension of the alveoli.

Optimizing Positive End-Expiratory Pressure (PEEP) is crucial as well; appropriate PEEP levels help to recruit collapsed lung units, improve functional residual capacity, and maintain oxygenation without exacerbating barotrauma, which refers to injuries caused by pressure differences. This careful management is essential because ARDS is often characterized by stiff lungs and impaired gas exchange.

Ensuring adequate oxygenation while preventing barotrauma is a vital part of ARDS ventilatory management, as patients need sufficient oxygen delivery while minimizing the risk of injury from mechanical ventilation. This involves using techniques such as lung-protective ventilation strategies and careful monitoring of airway pressures.

In summary, the correct answer reflects a well-rounded approach to ventilatory strategy in ARDS management, incorporating the principles necessary for protecting lung function while ensuring adequate oxygen delivery.
