对脊髓损伤后1周、3周、5周、3个月和5个月内的患者进行肺功能测量。在 C5 和 C6 段之间脊髓功能性完全横断的患者中，受伤后第一周的肺活量为预测值的 30%。 C4 损伤的患者肺活量较小。受伤后 5 周内肺活量显着增加，受伤后 3 个月肺活量大约翻倍。呼气流速直接取决于肺活量。在急性期，即使通气能力充足、碳酸水平正常的患者，动脉低氧血症的发生率也很高。
Measurements of pulmonary function were made on patients within 1 wk, 3 wk, 5 wk, 3 months, and 5 months of spinal cord injury. In patients with functionally complete transection of the cord between segment C5 and C6, the vital capacity was 30% of predicted in the first week after injury. Patients with injuries at C4 had smaller vital capacities. A significant increase in vital capacity occurred within 5 wk of injury with an approximate doubling of vital capacity 3 months after injury. Expiratory flow rates were directly dependent upon vital capacity. There was a high incidence of arterial hypoxemia, in the acute stage, even in patients with adequate ventilatory ability and normocarbia.
