Final answer:
The correct CPR ratio for a 6-year-old in 2 person CPR is 15 compressions to 2 ventilations, option b. 15-2.
Step-by-step explanation:
The proper CPR cycle of chest compressions to ventilations in 2 person CPR for a 6-year-old is 15 compressions to 2 ventilations, which corresponds to option b. 15-2. During CPR, providing adequate oxygenation while ensuring sufficient circulation is vital for survival. For a child from the age of 1 until puberty, the recommended CPR procedure by healthcare professionals involves one rescuer performing compressions while the other prepares to give breaths, allowing for quick alternation between the two tasks.
When two rescuers are present, one performs the chest compressions, and after every 15 compressions, the other gives two breaths, keeping in line with the importance of both ventilation and circulation for the child's survival.
