Remain Conscious was a Control-based Force ability which allowed a force-user to fight off damage effects that would knock out a normal individual.
A Force user could use the Force to Remain Conscious after being incapacitated through injury or some other means. However, they were severely limited in the actions that they could perform, sometimes only capable of performing one task before lapsing into unconsciousness. Force users who were able to use Control Pain to suppress the effects of the injury after using Remain Conscious could continue to function without being knocked out.
