Step 1: Understanding the Concept:
CPR for children differs slightly from adults because children often experience cardiac arrest due to respiratory issues. Therefore, the "Rescue breaths" are highly critical.
Step 2: Detailed Explanation:
1. Check for Response and Breathing: Tap the child and shout. Look for normal breathing.
2. Chest Compressions (C): If no response, start compressions immediately. Use one hand (for small children) or two hands (for older children) in the center of the chest. Compress about 2 inches deep.
3. Airway (A): Open the airway using the head-tilt, chin-lift maneuver.
4. Breathing (B): Give 2 gentle rescue breaths (1 second each) until you see the chest rise.
5. Ratio: Use a cycle of 30 compressions followed by 2 breaths.
6. When to Call: If you are alone and don't have a phone, perform 5 cycles (about 2 minutes) of this ratio before leaving the child to call for help and getting an AED. This is because providing oxygen quickly is vital for children.
Step 3: Final Answer:
The procedure involves 30 chest compressions followed by 2 breaths. A lone rescuer must perform 5 cycles of this before pausing to call emergency services.
