The correct technique for providing CPR on a child or adult involves the following key steps: For Adults:
- Place the person on their back on a firm surface.
- Perform chest compressions with the heel of one hand on the lower half of the breastbone at the center of the chest; place the other hand on top and interlock fingers.
- Keep arms straight and use body weight to press down about one-third of the chest depth.
- Compress at a rate of 100 to 120 compressions per minute.
- After every 30 compressions, give 2 rescue breaths by tilting the head back, lifting the chin, pinching the nose, and blowing into the mouth until the chest rises.
- Continue cycles of 30 compressions and 2 breaths until the person recovers or emergency help arrives.
- If unable to give breaths, perform continuous chest compressions only.
For Children (over 1 year old):
- Place the child on their back and kneel beside them.
- Use the heel of one or two hands (depending on child’s size) on the lower half of the breastbone.
- Compress about one-third the chest depth at a rate of 100 to 120 compressions per minute.
- Give 2 rescue breaths after every 30 compressions, with airway opened by tilting the head and lifting the chin, pinching the nose closed.
- Continue until the child recovers or help arrives.
For children, it is emphasized to give rescue breaths because breathing issues are more common in children than adults. These guidelines follow a "30:2" sequence (30 compressions followed by 2 breaths) and aim for compressions at around 100 to 120 per minute, with careful attention to hand position, compression depth, and airway management during rescue breaths.
