You are by the side of a patient who fell 5 feet from a ladder, landing on a concrete porch and hitting his lower back and buttocks. Assessment reveals an intact airway, adequate respirations, rapid radial pulse, and skin that is pale, cool, and diaphoretic. The patient complains of lower back and left leg pain. No deformity to the extremity is noted; however, the lower back is tender on palpation. The following vital signs are obtained: pulse, 132; respirations, 20 breaths/min; blood pressure, 102/88 mmHg; and SpO2, 97% on room air. Regarding oxygen therapy, you would:
