A 70-kg, 22-year-old man who is unconscious after a closed head injury is to undergo emergency splenectomy. He is anesthetized with thiopental, given pancuronium for paralysis, and started on nitrous oxide and oxygen 50% each with controlled ventilation (tidal volume 700 ml, rate 10/min).

- (D) Increase tidal volume to 1000 ml, increase FiO2 to 1.0
- (E) Increase tidal volume to 1200 ml, decrease respiratory rate to 8/min
