The diver continued to improve slowly upon returning home.
He was tested for a patent foramen ovale (PFO), and the results were positive. The diver elected to have the PFO closed. The procedure took place nearly nine months following the DCI incident. Six months after the procedure, the diver was given the clearance to dive on the proviso he followed the following guidelines:
• Conservative dive limits
• Maximum depth of 30 metres
• No more than two dives per day
• Minimum surface intervals of two hours, but the longer the better
• Nitrox to be used where possible (on air settings)
• Slow ascent and safety stops on all dives
• Evacuation by air
ambulance: US$11,800 • Treatment (chamber and hospital): US$10,650 All costs were fully covered by DAN under the Member’s coverage option.
