How long should you perform cardiac massage and artificial respiration to a person injured in an accident?

Explanation
Correct answer: Until the person regains their breath or is handed over to a paramedic.
In accordance with the principles of first aid, cardiopulmonary resuscitation should be performed continuously to maintain the casualty's basic vital functions. These actions should only be stopped when the injured person regains normal breathing or when professional medical services arrive and take over the rescue efforts.
