First aid was given to the sick and injured until they could receive proper medical treatment,
Many of the Doctor's companions, including Jo Grant, (TV: The Green Death) Tegan Jovanka, (AUDIO: Secrets of Telos) and Lucie Miller, (AUDIO: Flashpoint) were trained in first aid, Tegan as part of her training to become a stewardess, (AUDIO: Secrets of Telos) and Lucie while in the Girl Guides. While the Doctor noted that Tegan's skills would be of little use for treating a Trakenite, (AUDIO: Secrets of Telos) Lucie was able to resuscitate Elric, the son of a judge she was shepherding to safety, by means of CPR after he was struck by lightning on Cerberin.
