Case Example:A 33-year-old diver did a 40m multi-level dive within his computer limits and included a safety stop. After a surface interval of 1.5 hours, he then dived to a maximum depth of 47m. After ascending slowly to 20m, he ran out of air and did a rapid, uncontrolled ascent to the surface.Ten minutes later, he noticed tingling in his chest and legs, which developed to pain and weakness in the legs making him unable to walk. As there was no oxygen equipment on the boat, he was given 29% oxygen from a nitrox tank using a dive regulator (His nose was not blocked so he would have been breathing far lower than 29% oxygen). He was taken to the nearest hospital. DAN was called and advised on oxygen administration and arranged for recompression.After receiving five treatments, he was able to stand and walk again, but was left with some leg weakness, numbness and mild incontinence all of which have been improving with physiotherapy and time.Analysis:There are several issues that enhanced the severity of this diver's condition -- while there is little good evidence that "reverse profile" diving increases risk, many of us who have dealt with DCI cases believe that it well could unless carefully compensated for. Certainly the rapid ascent would likely have caused greater formation of nitrogen bubbles in the tissues and blood. Finally, the concentration of the O2 was too low to be effective (poor oxygen first aid). It was fortunate that the multiple recompression treatments were successful and the diver was able to walk again.
