Cardiopulmonary resuscitation (CPR) is a crucial medical technique that is performed manually to preserve intact brain function. Early initiation of CPR manoeuvres and activation of the chain of survival are key factors in the prognosis of patients with cardiorespiratory arrest (CRA). Inadequacy in any step of CPR due to a lack of knowledge or skill is associated with a poor return of spontaneous circulation and a decreased survival rate.
