Question

The Ratio of Compressions to Ventilations when one rescuer applies CPR to an Adult is?

1) 15:1
2) 15:2
3) 30:1
4) 30:2

Answer 1

The correct ratio of compressions to ventilations in adult CPR by one rescuer is 30:2, with an emphasis on high-quality chest compressions to maintain critical blood flow.

Step-by-step explanation:

When one rescuer applies CPR to an adult, the correct ratio of compressions to ventilations is 30:2. This means that the rescuer should give 30 chest compressions followed by 2 rescue breaths. Performing high-quality chest compressions is essential, as current standards recommend a compression depth of at least 5 cm and a rate of 100 compressions per minute to maintain blood flow, especially to the brain to prevent irreversible damage.
