We have studied the FVC and maximum flow-volume loop in 20 tetraplegics and the results have been compared with the predicted normal values. The FVC in sitting position is reduced at approximately half the normal predicted values and is significantly lower than in supine and Trendelenburg. At high lung volumes the flows are reduced at half the normal values. At low lung volumes the reduction is smaller (71.5 per cent).
我们研究了20名四肢瘫痪患者的用力肺活量（FVC）和最大流量-容积环，并将结果与预测的正常值进行了比较。坐位时的FVC约为正常预测值的一半，明显低于仰卧位和头低脚高位时的值。在高肺容量时，流量减少至正常值的一半。在低肺容量时，减少幅度较小（71.5%）。
