>DAN encourages each dive operator, scientific group or organization to work with local medical authorities to develop their own specific policy. There are problems and advantages to either approach. Again based on our experience at DAN, neither the “wait and see” approach nor the “prophylactic oxygen” approach has been verified to alter any outcome. DAN is available for consultation to any group or organization that develops a policy. We can provide the contact information for local dive medicine experts to also assist in policy conception. If we can be any further assistance do not hesitate to contact DAN.
