a. Not at all, so long as the airway is clear of obstructions and there is a route to the outside air. In this case the large neck wound and the open end of the cut treachea.
b. If that were the only wound there would be no limit, it's the same as a tracheostomy.
However breathing would be effected by the other wounds, and the effects there of.
c. It has already been posted by Kjab3113, with references, the time it would take to loose 50% of the blood volume, by either the Neck wounds or the Abdomen.
At this level of loss the heart would fail approx 3-4 after the cut.
This would obviously mean that if breathing had not already stoped at that point it would very soon after.
d. The blood flowing from the severed blood vessels in the Neck could cause serious problems with regards to breathing. Blood may well have flowed into the open trachea,. If such did occur, and it very possibly did, this would make breathing very difficult, the normal initial response to this would be increased attempts by the lungs to draw move air in. They may be heavy chest movements and gasping sounds. The condition described by Paul is very different to that, at one point he says it's as:
"as might be be felt in a child two or three months old"
The above views on the effect of the cutting of the windpipe are supported by Doctor Biggs who responded to a similar question from Trevor Marriott, most recently republished in Jack the Ripper - the real truth @2017
We have not even touched on the suggestion that Nichols may have been partially or fully strangled before the cutting took place.
It seems clear from the above and in the absence of alternative arguments that to suggest that breathing as described by Paul could place the time of death within a minute or two is unsupported.
However it does fit with the attack having taken place within 5 minutes of the discovery, and probably a little soon in line with the bleed out times suggested earlier.
This of course cannot exclude Lechmere if he was on site earlier than he claims; but it cannot place him there either.
