Cardiac arrest

In cardiac arrest, the heart stops pumping blood to the brain. Within minutes, the body's vital organs are starved of oxygen. Sudden cardiac arrest can happen to anyone. Learning CPR can save lives.

  • Call 112 and tell them where you are and what has happened.

  • Carry out cardiopulmonary resuscitation (CPR) to keep the victim's blood flowing until emergency services arrive.

  • Lay the person on their back. Kneel beside the person and place one palm in the centre of their chest. Place your other palm on top of your hand. This should be just above the breastbone.

  • Keep your arms straight. Press down on the person's chest at least 5–6 centimetres with quick, regular pressure, about twice per second. Use the weight of your upper body to make it less strenuous. Allow the chest to return completely between each press. Continue until the ambulance crew arrives.

  • Perform CPR to maintain blood circulation in the victim until medical personnel arrive.

  • Use a defibrillator if there is one nearby. The machine detects whether the heart is beating and delivers an electric shock if necessary.

  • Do not leave the scene until help arrives. Follow the instructions of the police and emergency services.
