The aim of this investigation was to study the effect of environmental pressure and surface tension on the size of gas bubbles in tissues and on their inner pressure. Due to the action of surface tension, the pressure inside the bubbles is always greater than the surrounding pressure. This phenomenon is the more marked, the smaller are the bubbles. Therapeutic compression leads to diminution of the volume of gas bubbles and thus to a rise of that portion of their inner pressure which is due to surface tension. In small bubbles the surface tension may cause their dissolution and disappearance. It is therefore correct to implement therapeutic compression in decompression sickness as soon as possible before the fusion of a significant number of small bubbles into larger ones occurs.
本研究的目的是探讨环境压力和表面张力对组织中气泡大小及其内部压力的影响。由于表面张力的作用，气泡内部的压力总是大于周围的压力。气泡越小，这种现象越明显。治疗性加压会导致气泡体积减小，从而使由于表面张力引起的那部分内部压力升高。在小气泡中，表面张力可能导致它们溶解和消失。因此，在减压病中，在大量小气泡融合成大气泡之前尽快实施治疗性加压是正确的。
