在7条狗身上测量了减压形成的血管内气泡的14种大小分布。使用Stokes方程通过终端上升速度技术估计较大的气泡，同时使用Coulter计数器确定较小的气泡。记录到直径为19 - 700微米的气泡，这些气泡以数百个簇射的形式到达静脉窦，其平均尺寸随着减压后时间的延长而增加。平均直径比以前尸检记录的要小。讨论的结果表明，所有静脉气泡的大小范围内，他们将被肺过滤掉，除非这个器官已经绝缘。
Intravascular bubbles formed by decompression have been measured in 7 living dogs to give 14 different determinations of size distribution. Larger bubbles were estimated by the terminal rise velocity technique using the Stokes equation, while smaller bubbles were determined simultaneously, using the Coulter counter. Bubble diameters of 19--700 micrometers were recorded, these reaching the venous sinus as showers of several hundred whose mean size tended to increase with post-decompression time. Average diameters were rather smaller than previously recorded from autopsy. The results are discussed as indicating that all venous bubbles were within a size range where they would be filtered out by the lungs unless this organ had been insulated.
