Final answer:
The correct compression-ventilation ratio for 2-rescuer child CPR is 15:2. This involves 15 chest compressions followed by two ventilations, repeated steadily to sustain blood circulation.
Step-by-step explanation:
The compression-ventilation ratio for 2-rescuer child CPR is 15:2. During a CPR situation, two rescuers are recommended to work together to perform chest compressions and provide ventilations to a child who has suffered cardiac arrest. The designated compression provider will carry out 15 chest compressions followed by two ventilations, which are provided by the second rescuer. This cycle is repeated consistently to help maintain blood flow to the child's brain and other vital organs until emergency medical services can take over.
It's important to note that high-quality chest compressions greatly contribute to the patient’s survival. According to current standards, chest compressions should be at least 5 cm deep and at a rate of about 100 per minute. While performing CPR, the rescuers should aim for minimal interruption between compressions and ventilations to maintain consistent blood flow.
