Cardiopulmonary Resuscitation - CPR is used in an emergency if someone is not breathing normally, or their heart has stopped (cardiac arrest). This combination of techniques is used: chest compressions, and rescue breathing (mouth-to-mouth) CPR helps maintain vital blood flow to the brain and other organs, potentially preventing irreversible damage or death. CPR works on the principle of 30 chest compressions and 2 breaths of rescue breathing (moth-to-mouth) -known as 30:2).
