1) Open the baby's airway by placing one hand on the forehead while gently tilting the head back and lifting the chin. Remove any visible obstructions from the mouth or nose.
2) Place your mouth over the mouth and nose of the infant and blow steadily and firmly into their mouth, checking that their chest rises. Give five initial rescue breaths.
3) Place two fingers in the middle of the chest and press down by one-third of the depth of the chest. After 30 chest compressions at a steady rate (slightly faster than one compression a second), give two rescue breaths.
4) Continue with cycles of 30 chest compressions and two rescue breaths until they begin to recover or emergency help arrives.
