The specific compliance of the chest wall and lungs combined was measured in eight patients with stable tetraplegia. Expiration was impeded with a series of spring-loaded resistances, and end-expiratory pressures plotted against changes in chest wall volume at end-expiration. An optical contour mapping system was used to partition changes in chest wall volume into rib cage and abdominal components. These measurements suggest that the compliance of the whole system is reduced by one third in patients with stable tetraplegia, compared with normal subjects. This may be because of abnormal stiffening of the rib cage.
对八名病情稳定的四肢瘫痪患者测量了胸壁和肺部联合的比顺应性。通过一系列弹簧加载阻力阻碍呼气，并将呼气末压力与呼气末胸壁容积变化作图。使用光学轮廓映射系统将胸壁容积变化分为胸廓和腹部部分。这些测量结果表明，与正常受试者相比，病情稳定的四肢瘫痪患者整个系统的顺应性降低了三分之一。这可能是由于胸廓异常僵硬所致。
