A young female patient involved in a motor vehicle collision responds to painful stimuli by extending her arms and legs. Her airway is open, and her breathing is shallow and irregular. A radial pulse that is moderate in strength is palpated. Her pulse is 64 beats/min, respirations are 8 breaths/min and irregular, and blood pressure is 210/110 mmHg, with an SpO2 of 90% on room air. The patient has an obvious deformity to her forehead and a left pupil that is dilated and does not respond to light.
