Arterial oxygenation was studied in a control group as well as in patients with head and spinal cord injuries. While most of the control group had normal partial arterial oxygen pressure (Pao2), half of the group with trauma had Pao2 values below 80 mm Hg, and between 10% and 20% were significantly hypoxemic with Pao2 values below 60 mm Hg. Since the clinical recognition of hypoxemia is exceedingly difficult unless there is a profound fall in Pao2, and since hypoxemia may be present almost immediately after the injury, the patient's Pao2 should be determined in all cases of head and spinal cord injuries in order to institute proper therapy early.
