Decompression venous gas bubbles were detected with the precordial Doppler utrasound technique in humans at simulated altitudes of 1,000-3,000 m 3 h after no-stage decompression dives to 15 or 39 m. Bubbles were detected at 3,000 m in a total of 60% of the subjects: in 90% after the 100-min shallow dives to 15 m with some bubbles present in the first minutes (mean onset 12 min), and in only 30% after the 10-min deeper dives to 39 m with later appearances of bubbles (mean onset 28 min). At both 2,000 and 1,000 m bubbles could also be detected, sometimes in the first minutes. The risk of decompression sickness must be considered high with the amount of gas bubbles found, even though only uncertain symptoms appeared in this study. Thus, a safe interval between ordinary SCUBA-diving and flying in airliners or general aviation aircraft seems to be more than 3 h.
在模拟海拔1000 - 3000米高度时，运用心前区多普勒超声技术，对无阶段减压潜水至15米或39米后3小时的人体进行检测，发现了减压性静脉气泡。在3000米高度，总共60%的受试者检测到气泡：在100分钟浅潜至15米后，90%的受试者检测到气泡，且在最初几分钟就有一些气泡出现（平均开始时间为12分钟）；而在10分钟深潜至39米后，只有30%的受试者检测到气泡，气泡出现时间较晚（平均开始时间为28分钟）。在2000米和1000米高度也能检测到气泡，有时在最初几分钟就出现。尽管本研究中仅出现了不确定的症状，但鉴于发现的气泡数量，减压病风险必须被视为很高。因此，普通水肺潜水与乘坐客机或通用航空飞机飞行之间的安全间隔似乎应超过3小时。
