Final answer:
The first rescuer must check for responsiveness and call for help upon finding an unresponsive infant or child. After ensuring emergency help is en route, assess for breathing and circulation to determine if CPR is needed. Proper CPR involves chest compressions and possibly rescue breaths, while special attention is needed for choking or drowning incidents.
Step-by-step explanation:
The first rescuer arriving on the scene of an unresponsive infant or child should check for responsiveness and call for help. This means checking if the infant or child reacts to gentle stimulation or calling of their name. If there is no response, it's imperative to call for emergency assistance immediately before proceeding with further action.
Once help is on its way, it's important to quickly assess the situation. If the infant or child is not breathing and has no signs of circulation, cardiopulmonary resuscitation (CPR) may be necessary. The proper technique for CPR involves positioning the hands on the sternum, administering chest compressions at least 5 cm deep and at a rate of 100 compressions per minute, and providing rescue breaths if trained to do so.
In cases involving drowning, removing the child from the water and then starting CPR is critical, as it is ineffective in the water. If an infant is choking, attempting to dislodge the obstruction by turning the baby upside down and giving back slaps may be the appropriate first step before CPR.
