Final answer:
The correct compression to ventilation ratio for a 7-year-old child with 2+ rescuers present is 15:2, with 15 chest compressions followed by 2 ventilations.
Step-by-step explanation:
The correct compression to ventilation ratio for a 7 y.o. child when there are 2+ rescuers present during CPR (cardiopulmonary resuscitation) is 15:2. This means you should give 15 chest compressions followed by 2 ventilations. This ratio is recommended for the effective resuscitation of children and is distinct from the guidelines for adults, which typically recommend a compression to ventilation ratio of 30:2. However, the scenarios provided do not directly relate to the correct compression to ventilation ratio; the respiratory rate of a child and other information provided is about normal or pathological respiratory conditions, not emergency resuscitation protocols.
