Start CPR by giving 30 chest compressions and two breaths (30:2). Aim for approximately 100 to 120 chest compressions per minute.

1. Place the heel of one hand in the centre of the chest on the lower half of the breastbone. Then place your other hand on top.
2. Give 30 compressions by firmly placing down by one-third of their chest depth.
3. Open their airway by tilting the head with a chin lift, then:
   1. Pinch their nostrils to create a seal
   2. Blow steadily into their mouth for 1 second – watch for the chest to rise and fall. Take a breath and blow it into their mouth again.
4. Now repeat these steps again with 30 compressions, followed by two breaths (30:2)

Continue CPR (30:2) until the ambulance arrives or they recover.
