It could be argued that this is a similar question, Did Darth Sidious and Vader ever discover how to cheat death?, but this seems to be more in line with spirit and conscious transference etc.
What I am curious to know is, can or has a Sith/Jedi used the force to keep someone alive physically?
We see plenty of examples of Sith phyiscally taking lives with the use of the force and I was hesitant to include them in this question as they don't seem like ideal candidates to help someone. But there is the issue with Anakin on Mustafar after he suffers those terrible injuries and Darth Sidious coming to his rescue. I am not sure if Darth Sidious actually kept him alive until the medical pod arrived. Or if he just was there to show his presence to Anakin.
eg: Someone suffers an injury that stopped the person/life forms heart and a Sith/Jedi used the force to physically keep the heart beating while waiting for medical assistance to arrive. Once arrived, then being put on some sort of life support. ie, if the Jedi or Sith was not there they would have normally died.;
So was there any canon examples of the Sith/Jedi physically keeping someone alive by using the force?
