All precautions should be taken to avoid decompression illness, but if illness is suspected the hospital staffs in the Keys are very experienced with diagnosing and treating it. Divers suspecting decompression illness should seek medical attention immediately at one of the Keys hospitals The staff at these facilities know how to diagnose and treat the condition. If necessary, they will transfer patients to one of two decompression facilities in the Keys. The U.S. Military operates a decompression chamber in Key West. The more-often used facility is located in the Upper Keys at Mariner's Hospital.
