Similar incident off Jeddah earlier this year (or late last year), an Instructor switched from air to 100% O2 at depth in front of two students!I watched a person die swapping regs at depth, when he mistakenly switched to o2.

Extremely doubtful, considering they skimped on treatment & didn't know who to contact for dive-related-medical-advice.I really hope he has DAN insurance. A guy recently did a very pedestrian chamber ride in a hospital chamber in the Miami area that would have been ~$40K... but he had DAN so completely covered. This kid is going though something much more extensive.
+100. The #1 reason I got DAN was ensuring I get the right expertise and treatment quickly, and #2 was financial, and to remove any incentive to not get checked out.Personally, I would call DAN first. If they think you have possible DCS, they will get you going to the correct facility .... EMTs and emergency room to which he was taken refused to give him early treatment for DCS no matter how much he begged for it.
Good thinking, I might have to do that soon as well. It's like an insurance policy you only have to buy once (with minimal upkeep).See my post above about 8hrs in ER with nothing at all. Part of why I now have a O2 kit.
This may have been answered (I'm catching up on posts) "But did it actually make things worse in this case?"So the IWR attempt was unwise, to say the least. But did it actually make things worse in this case? Or was the problem just their refusal to seek the proper treatment, which continued for hours after they returned to shore anyway?
I'm going to have to disagree with some nuance. Switching regs itself shouldn't be dangerous to a scuba-diver. Yes, you can do it improperly, but it's generally safe. It's safe enough it's even taught to beginner open-water divers. With sidemount, you're switching tanks/regs VERY frequently.Using twin independent doubles where one has to switch regs to balance out the pressures is an accident waiting to happen at the best of times! And especially so at depth!!

And then a close relation of mine almost died / got bent real bad from exactly what you describe above, that is although he thought he was switching regs he kept, 'seemingly' (as I wasn't there), putting the same one back in his mouth. When that cylinder ran out, and being obviously incapacitated in the 50-60m zone on air, he tried to ascend, passed out, and floated back down where another diver/s found him. They got up him up and back on the boat missing all his deco and 'seemingly' dead, manage to get some life back into him by the time the chopper arrived, and long story short, it turned out to be a case where they thought he would not survive, but he proved them wrong although his diving was over for some years, and his deep diving days were over, period. But now we digress from the thread at hand..
@Dr Simon Mitchell, thanks for the answer re the IWR kit photo, and Miria says to say hi!
First how often do you think those open water divers practice switching regs (rhetorical question).I'm going to have to disagree with some nuance.

Any danger from reg-switching or independent air-sources is usually something else.
- Forgetting how to properly switch regs (purge), lack of practice, unable to find reg.
- Not monitoring air, or not switching when a tank runs out.
- Switching to the wrong gas/tank.
- Panicking and just doing the absolute wrong thing.
I'm answering the rhetorical question anyway. Not often, which is a potential danger, and I'm advocating people do practice, so to eliminate that problem.First how often do you think those open water divers practice switching regs (rhetorical question).
Re-reading your post several times, are you referring to a scenario, where someone has back-mount-independent doubles, and different gasses in each tank? That specific scenario is dangerous.Second, the above list is exactly what I am talking about as 'problems / downsides' of using independent doubles (and yes, as you say, there are ways to at least minimize those problems, but not everyone does that).
To your first question the answer is no, same gas (air)..Re-reading your post several times, are you referring to a scenario, where someone has back-mount-independent doubles, and different gasses in each tank? That specific scenario is dangerous.
For the rest, I assert that has nothing to do with reg-switching or independent air-systems.
Grandma died too?? wow. Very bizarre mother.... I feel bad for the kid
oh wow I did not release that only a few Hospitals in Florida will treat DCS. I figured that since its such a popular dive destination most of the Hospitals would treat, but I guess they all don't have chambersWell he is at the right place, Blake is one of the few hospitals in Florida that will treat DCS.
What am I missing from the video? It won't load.
I could try to verify it, but TBH I have very limited contact with the local scuba community outside the rare tank fill or getting stuff serviced.
