Neither document states whether they were conscious when they were gasping. That's important to know when determining if the method is peaceful.
They were unconscious well before. Both the prosecutor and the pro-choice doctor were in good part right. Unconsciousness happened in under a minute and could have triggered slightly quicker if their mask seal was perfect (hypothesis). To note, they believe that unconsciousness, based on visual observations (or "communication" interrupted - not responding to talk), is not a perfect duty to assess, but I'm hoping if their judgement was approximate, it's a matter of seconds (and they don't mean anything else).
Past this stage, there's some grim, but peacefulness is normally locked by now.

this is representative of the Exit Bag method. Now I'm making a
fundamental difference...
The chance at nausea/vomiting has put me off entirely of this method, too bad , it sounded very promising. Same with gas it seems.
Regarding vomiting, here is one evidence with
exit bag
I do NOT understand the last line. Why would you suffer if unconsciousness is reached after 10-12 seconds ? Would you retrieve some consciousness and choke ? Meh !
Based on the sorted onset of progressive hypoxia symptoms, I would believe that it's a rare minor discomfort concern because it will come last with the R2D, likely ...too late to realize ! Vomiting is generally mentioned a lot less ...than nausea
If by "gas" you meant "exit bag". I'd disapprove. If you want a close certitude to skip feeling sensations (bad ...or good), the exit bag seems the way to go.
Here it says that poor mask fitting increases the time to achieve unconscioussness, first, and then death. But nothing else, it doesn't tell about permanent sequelae. So, I don't know why it's also said "Oxygen deprivation with a face maks is not acceptable because leaks are difficult to control and it may not eliminate rebreathing". When immediately it's said "These factors will extend time to unconsciousness and time to death". This is the important factor, if the poor mask-fitting only increases the time to unconsciousness and time to death that it's not a problems. A problem would be permanent sequelae.
They clearly explain there are 2 possible set of conditions to achieve the goals. One structure looks very close to the description of the R2D system, and the other one to the classic Exit Bag. Yet, they went just slightly in between (choice of a face mask somewhat imperfect - they found out, without a recycling mechanism ...their rebreathing dilemma was only about the fit)
My judgment is that they value the simple apparel of a hood (plastic bag) with proper gas flow flushing the gases out, as a robust design that shouldn't go wrong (less surprises = less worries). Their "complaint" about using a mask appears rhetorical because it did not have an impact in their cases, but they imagine it could eventually be a less fool proof setup than a hood. They try to explain it, as motivated but it is unclear if the concern is realistic (imho). The final word is they haven't tested a ReBreather unit... but I'm also not meaning they would have liked its bulkiness more, given the arguments. Just - can't - answer.
(Initially, the R2D is also not an oxygen free environnement. It's here to achieve it.)

The possibility of sequels is never brought about. They just clearly write that permanent brain damage will happen right before death. Consequently, same same than usual, a focus to eradicate rescuing should not be disregarded.
