Final answer:
In the event of respiratory arrest in a child under 8, call 911 immediately, then initiate CPR with chest compressions and rescue breaths if you're trained, or chest compressions only if not trained. Perform these actions until help arrives or the child recovers.
Step-by-step explanation:
During respiratory arrest in a child under the age of 8, the proper steps to take include immediately calling 911 to get professional help on the way. After calling for help, you should start cardiopulmonary resuscitation (CPR) if you are trained to do so. This involves delivering chest compressions and rescue breaths, if you have been trained in rescue breathing. If you have not been trained in CPR, performing hands-only chest compressions at the rate of 100 per minute (to the beat of the song "Staying Alive" by the Bee Gees) is recommended until professional help arrives.
It is critical to remember that while delivering CPR, the Heimlich maneuver should only be performed if you are certain that an obstruction (such as a piece of food) is causing choking and airway blockage. If the child is unconscious, always ensure that they are on a firm, flat surface before beginning chest compressions. Proper hand placement on the sternum between the lines at T4 and T9 is essential to effectively compress the chest without causing harm. Rescue breaths should follow the compressions, particularly if you are trained and able to provide them. Continue these efforts until professional help takes over or the child recovers.
