Cardiopulmonary resuscitation (CPR) is an emergency procedure performed on a person in cardiac arrest. CPR combines chest compressions often with artificial ventilation in an effort to manually preserve a supply of oxygen to the brain until further measures are taken to restore spontaneous blood circulation and breathing. Anyone can be trained to do CPR, it is a very simple skill, and could mean the difference between life and death.
One of the most successful skills that a first aider can learn is the treatment of choking. Things such as food, sweets, or small objects can easily become lodged in the airway if they are accidentally 'breathed in' rather than swallowed. Recognising that someone is choking it essential to a successful outcome.
