A 47-year-old, 6'1" male patient is admitted to the hospital due to trauma from a motor vehicle accident. Forty-eight hours post admission, the patient is suffering from respiratory distress with severe hypoxemia and is intubated

A chest X-ray, done prior to intubation, reveals a ground glass appearance bilaterally. The physi-cian requests the volume-controlled continuous mandatory ventilation (VC-CMV) mode for this patient. The initial settings for the ventilator should be which of the following? a. VT = 450 mL, rate = 18 breaths/min, PEEP = 8 cm H2O b. VT = 600 mL, rate = 10 breaths/min, PEEP = 5 cm H2O c. VT = 750 mL, rate = 15 breaths/min, PEEP = 10 cm H2O d. VT = 900 mL, rate = 12 breaths/min, PEEP = 5 cm H2O
