A pаtient whо just suffered severe clоsed-heаd injury аnd has a high intracranial pressure (ICP) is abоut to be placed on ventilatory support. Which of the following strategies could help to lower the ICP? A. Maintain a PaCO2 from 25 to 30 mm Hg (deliberate hyperventilation). B. Allow as much spontaneous breathing as possible (SIMV). C. Maintain a high mean pressure using PEEP levels of 10 to 15 cm H2O. D. Maintain a PaCO2 of 50 to 60 mm Hg (deliberate hypoventilation).

The high-pressure limit alarm will sound (if properly set). B. The patient will continue to receive 10 breaths/min. C. The low tidal volume (VT) alarm will sound (if properly set). D. Ventilation will drop to zero and the apnea alarm will sound.
