Anesthetized rabbits were exposed to blunt impact on the right chest wall. The controlled impact was delivered with a special machine equipped with a captive piston driven by a freely falling weight. Chest wall deflections were recorded in order to study the effects of magnitude and rate of deformation of the thorax on the resulting lung injury. The ranges of magnitude and rate of deformation corresponded to an inward deflection of the chest wall of about 5-60% of the lateral diameter of the chest, and to a velocity of the chest wall of about 2-20 m/s. Impulses delivered to the chest and intrathoracic pressures were also studied. Severe hemorrhages in the lungs were produced at velocities of the chest wall exceeding about 10 m/s. For velocities of the chest wall below about 5 m/s, lethal injuries were produced without severe hemorrhages in the lungs.
将麻醉后的兔子右侧胸壁暴露于钝性撞击。通过一台配备由自由落体重量驱动的俘获活塞的特殊机器施加可控撞击。记录胸壁偏转情况，以研究胸廓变形的幅度和速率对由此产生的肺损伤的影响。变形幅度和速率范围分别对应胸壁向内偏转约为胸廓横向直径的5% - 60%，以及胸壁速度约为2 - 20米/秒。还研究了传递至胸部的冲量和胸内压力。当胸壁速度超过约10米/秒时，肺部会出现严重出血。对于胸壁速度低于约5米/秒的情况，会产生致命伤，但肺部无严重出血。
