Wright SSVA HS CPR And First Aid Practice Test

The proper compression to rescue breaths ratio for a 9-year-old child during CPR is 30 compressions to 2 rescue breaths. This specific ratio is recommended to ensure that adequate blood circulation is maintained while providing effective ventilations. When performing CPR on children, the cycles of compressions and rescue breaths are structured to maximize oxygen delivery and restore perfusion. The 30:2 ratio is established to align with the findings that a higher frequency of compressions is generally more effective in maintaining circulation, while two rescue breaths can help replenish oxygen levels more efficiently after a cycle of compressions. Adhering to this ratio assists in sustaining the vital signs of the child and provides the best chance of survival until advanced medical help arrives.
