Not just from that, no.

At some point, if there’s no underlying problem, the co2 levels in the blood will get high enough the involuntary system kicks in and you’ll take a breath, which will keep going.

Now, there are health conditions that can interfere with that, and something environmental might cause a problem, but assuming none of that is the case, all those good samaritans did was make it happen sooner.

You can choke someone out, and they’ll still breathe eventually.

If you “Burke” someone, that’s a different story, but even then it’s still possible for the autonomic breathing to kick back in.
