I am trying to better understand what usually happens from a medical stand point when a fighter (MMA, boxer or otherwise) is rendered unconscious during a bout. Although unrealistic, to simplify things and keep this question focused, let's assume that the fighter has no other injuries and has only been rendered unconscious eg. via a sleeper hold.
At this point what usually happens to them as they lay there? For example, if they do not regain consciousness on their own I would assume a medical team will start trying to resuscitate them immediately, or is that up to the fighter's team to have someone that can do that onboard? Once successfully resuscitating them, does the fighter then have to spend some mandatory time in a hospital or in the care of some other physician to make sure they're ok, or are they free to head on home straight after the bout?
I've been watching a few greatest MMA knockouts videos and it has made me wonder how on Earth some of those guys get home afterwards.
