- Always call for an ambulance before starting CPR.
- Continue CPR until emergency medical services arrive.

Understanding CPR
CPR is short for cardiopulmonary resuscitation.
If a child stops breathing normally or their heart stops, doing CPR can keep their body going until an ambulance arrives.
When you do CPR, the chest compressions and mouth-to-mouth (rescue breaths) help circulate blood and oxygen in the body.
When Should You Perform CPR?
You should start CPR if a baby or child:
- is not moving and does not respond when you call them or tap their foot
- is not breathing normally
Start CPR as soon as possible. Try to stay calm. CPR can save a child’s life.
Step-by-Step Guide to Performing CPR
There are some differences in how to perform CPR and first aid for babies and children compared with adults.
For both adults and children/babies, you will use the same ratio of chest compressions and rescue breaths: 30 chest compressions for every 2 mouth-to-mouth breaths.
Follow these life support steps before starting. (Use the phrase DRS ABC to help you remember the steps.)
| Letter | Representing | What to do |
|---|---|---|
| D | Danger | Ensure that the child/baby and all people in the area are safe. Do not put yourself or others at risk — remove the danger or the child/baby. |
| R | Response | Look for a response from the child/baby. Check for a response to a loud voice, tap their foot or squeeze their shoulders. Do not shake the child/baby. |
| S | Send for help | If there is no response, call emergency services or ask someone else to make the call. Do not leave the child or baby unattended. |
| A | Airway | Gently lift the child/baby’s chin to a neutral position (with the head and neck in line, not tilted). Check in the mouth for any blockages (vomit, an object or loose teeth) and clear it out with your finger. |
| B | Breathing | Check if the child/baby is breathing abnormally or not breathing at all after 10 seconds. If they are breathing normally, place them in the recovery position and stay with them. |
| C | CPR | If they are still not breathing normally, start CPR. Chest compressions are the most important part of CPR. Start chest compressions as soon as possible after calling for help. |
- Perform 30 Chest Compressions
- Place the child/baby on their back on a firm surface.
- For children: Place the heel of one hand in the center of the chest. Put the other hand on top.
- For babies: Use two fingers to compress the chest instead.
- Keep arms straight and press down to one-third of the chest depth.
- Release the pressure—pressing down and releasing counts as one compression.
- Give Mouth-to-Mouth Breaths
- Tilt the head back slightly and lift the chin to open the airway.
- Open the mouth but avoid touching the neck.
- Take a breath and cover the child’s mouth with yours. Pinch the nostrils shut.
- For babies, cover both the mouth and nose with your mouth.
- Blow steadily for about 1 second and watch for the chest to rise.
- Release and watch for the chest to fall.
- If the chest does not rise, check for obstructions and ensure a proper seal.
- Repeat for a total of 2 breaths.
- Continue with the 30:2 CPR Cycle
- Give 30 chest compressions followed by 2 breaths.
- Aim for 5 sets of 30:2 in about 2 minutes.
- Maintain a rate of 100 to 120 compressions per minute.
- Use of Defibrillation (AED)
- If an automatic external defibrillator (AED) is available, attach it and follow the prompts.
- Do not use an AED on infants under 1 year of age.
Tools and Assistance
- First Aid Courses: Learning CPR through certified first aid courses is highly recommended. Make sure the course covers CPR and first aid for babies and children.
- CPR Fact Sheets: Various organizations provide downloadable fact sheets on CPR techniques that can be referenced in an emergency.
- Mobile Applications: Many apps are available that provide real-time guidance for emergency first aid procedures, including CPR.
