Verified step by step guidance

Step 1: Ensure the scene is safe before approaching the child to avoid any hazards that could compromise your safety or the child's safety.

Step 2: Check for responsiveness by gently tapping the child and shouting to see if they respond. If there is no response, proceed to the next step.

Step 3: Assess the child's breathing and pulse. Look for chest rise and fall to determine if they are breathing, and check for a pulse by palpating the carotid artery (located on the side of the neck).

Step 4: If the child is not breathing and has no pulse, immediately begin CPR, starting with chest compressions. Use the appropriate compression depth and rate for an 8-year-old child (approximately 2 inches deep at a rate of 100-120 compressions per minute).

Step 5: If an Automated External Defibrillator (AED) is available, retrieve it and follow its instructions while continuing CPR until emergency medical services arrive or the child shows signs of recovery.
