Question

Quizplus · Accepted Answer

When a patient develops ARDS, ventilation with large tidal volumes can cause further lung injury. Current guidelines recommend using a low tidal volume ventilation strategy, typically set at 6 mL/kg of predicted body weight. For this patient weighing 68 kg, a tidal volume of 400 ml would be appropriate (6 ml/kg x 68 kg = 408 ml, rounded down to 400 ml). Therefore, the correct answer is B) 400 ml.
