Start chest compression as follows:
o Kneel by the side of the victim.
o Place the heel of one hand in the centre of the victim’s chest
(which is the lower half of the victim’s sternum (breastbone)).
o Place the heel of your other hand on top of the first hand.
o Interlock the fingers of your hands and ensure that pressure is not
applied over the victim's ribs. Do not apply any pressure over the
upper abdomen or the bottom end of the sternum.
o Position yourself vertically above the victim's chest and, with your
arms straight, press down on the sternum 5 - 6 cm.
o After each compression, release all the pressure on the chest
without losing contact between your hands and the sternum.
Repeat at a rate of 100 - 120 min
o Compression and release should take an equal amount of time.
