CAVE DIVING: Being a diver is bad enough, what with the risk of decompression, which can cause failure of the spinal cord, brain and lungs.
洞穴潜水：潜水本身具有减压的危险，容易引起脊髓、脑、肺功能衰竭，已经够可怕的了。

I am a diving medical officer of the Dutch army. One of the methods of professional diving is with surface decompression, using oxygen for a faster decompression.
