You also run into another problem: Who am I to hold a diver down?
If they want to race up, should I really stop them?
If they want to race up, should I really stop them?
What do you do when donating to a panicked diver who initiates a buoyant ascent?

Nah my ex instructor mate, instructor not mate he's an amazing diver, a cross between a frog and a fish
little guy, I carried him across the threshold into reception at a resort we were diving at on my shoulder
and he still thanks me for ducking, well him and a student having spent a bit of time at eighteen metres
were going ballistic up a whoops not panic just accidentally up ballistically anyway it was only a shop BC
Stab slash hack, back to the boat off to the pub

Do you have a reference link for more information on this? I've never heard of the epiglottis seizing closed before.
I watched an instructor punch a guy in the stomach to get an individual to breathe when the guy "locked up"....
There are many ways for people to want gas/a way out. However, I am not sure the likelyhood of someone doing the rational act of "asking for gas" and then bolting to the surface without some kind of signals. (Not conscious, but ways of acting). However, on a rec dive, I would follow them up. The likelyhood of them having a medical emergency or not being able to establish positive buoyancy on the surface are in my very personal mind far greater than me having a non-treatable hyperbaric event from an ascent from 15m on a rec dive. I have a slightly sketchy history with misplaced bubbles on shallow fast ascents, but hey... thats a bit of an itch. Lungs are fine. Ears can take a beating. I would rather follow, make sure my friend is ok, and fiks the rest in the pub/knit-cafe afterwards.
So... to do something about it. This should not be a surprise event.
Be a buddy. Be aware. Scan your environment, and pay attention to your fellow divers. Notice little quirks. Ask questions. If they prefer being behind you, is their light logically placed. Are they erratic? Nervous? Aches/Pains? Things that can be precursors for "events" under water. Be a thinking diver. Consider skill level. Consider the unspoken agreement. Do the handshake. Plan the plan. Plan what to do when the plan fails. Laugh at all the possible wayS THE plan could fail. And when you get up... laugh at the one that you didnt plan for to fail... that really did....
Control the narrative. Control where the lines go in your dives. Make it fair.
But ultimately... having being on the end of a fresh buddy loosing all control and sinking like a stone, to a place where he had neether gas, nor brain to be. He got a ride on the ImlaExpress. I almost gave up. I almost lost him. Had i let go, two fingres. I would not be here today.
so... before rambling to much
Excercise your basic awareness. Hvor er buddiene. Hvor er lyset dems? Kom de seg i vannet? Hadde vi noen avtale? Husker ikke. Poenget er... følg med på buddyen din, da får man ikke panikkbuddier fordi man har fiksa oproblemet for lenge siden.

Here, for example:
Physiology and Pathophysiology of Glottic Reflexes and Pulmonary Aspiration: From Neonates to Adults
Pulmonary aspiration is the consequence of abnormal entry of fluid, particulate material, or endogenous secretions into the airway. The two main types of aspiration scenarios include anterograde aspiration, which occurs during swallowing, and retrograde ...

All this stuff about avoiding the situation is good, but that is not the question. Something to consider- once the victim takes your regulator, you really, really do not want him cranking on the hose. He could tear the hose from your first stage. IF that were to happen the situation becomes very serious.
So for that reason, you don't want a tug of war, certainly don't plan on it. It is to your benefit to try to control the victim especially once they "got you by your hose".
If the diver grabs the reg and bolts, I would do my best to match his ascent speed, grab his harness, if they don't calm down, you are going for a ride. I would wrap my legs around their midsection in a scissor hold. This will lock you into a perpendicular position which allows you then to lean back a little, and extend legs and feet/fins and create as much drag as possible.
Then, if we are arising in a cloud of bubbles, you know the ascent rate is excessive and I would use one hand to hold the victim and the other to dump from my BC - I don't use a dry suit. I would concentrate on taking shallow breaths, so as to hopefully avoid a lung injury. If possible, I might also grab their BC inflator and try to dump on the ascent if it seems too fast and if you have access to it.
Once on the surface after a rapid ascent, you might want to snatch the reg and re-descend to 20 feet if you feel like nitrogen is an issue. Hopefully the victim won't die on the surface with a full BC.
I have actually done something very similar, ridding a diver up in a very buoyant situation. Doing the scissor hold keeps your body still and is not that strenuous.
