Definitely one perspective..."challenging" , "struggle", "outdated".....but we should be asking what is the alternative? If DAN can't have a contact listing of diver treatment chambers that are on-line and if those chambers can't or will not routinely and periodically update their status with DAN....again what is the alternative?
Is it not better to have a listing of chambers available for divers so that individual divers can utilize the list to verify the chamber status during the development and immediate emergency planning for a dive? Always comes back to individual responsibility of each diver, not operators or DAN, to ensure that before they dive they have an updated emergency plan in place and with them on the dive.
Even a phone number for these treatment chambers with a message line stating their current status would work; if we had the location, type and phone number of the diver treatment chambers. Nada now. Without that you abrogate your well being to a third or fourth party rather than assuming that responsibility yourself. Nobody has more skin-in-the-game than the injured diver.
DAN serves a function but they are limited by business decisions, resources and the proclivity of many divers to "let them" provide for our safety.
A listing of chambers and pressurized air ambulances by zones or regions in USA, regardless of current status, is in my estimation a minimum. Then each diver needs to step up and own our responsibility for our specific emergency plans tailored to meet the needs for each dive. To accomplish that we need the listing of needed resources to correctly and timely implement our specific emergency plan. Hope for the best but prepare for the worst. Or just hope for the best and see how that works out.
Again, I could be wrong.....
