Free CPR Techniques for Adults & Children Questions and Answers 1

Question 1

What is the correct compression-to-ventilation ratio for single-rescuer CPR on an adult?

Accepted Answer

30:2

Answer

For single-rescuer CPR on an adult, the correct compression-to-ventilation ratio is 30:2. This ratio prioritizes continuous, high-quality chest compressions to maintain vital blood flow. The two rescue breaths are delivered quickly after 30 compressions to minimize interruptions.

Question 2

How many rescuers are needed for the 15:2 compression-to-ventilation ratio in children?

Accepted Answer

2

Answer

Two rescuers are needed for the 15:2 compression-to-ventilation ratio in children. This ratio is used in two-rescuer CPR for children to provide more frequent ventilations, which are often more critical for pediatric cardiac arrest. The presence of two rescuers allows for more efficient delivery of both compressions and breaths.

Question 3

For child CPR, what is the recommended compression depth?

Accepted Answer

2 inches

Answer

For child CPR, the recommended compression depth is about 2 inches (5 cm), or approximately one-third the depth of the chest. This depth ensures effective circulation of blood to vital organs. It is important to achieve adequate depth while also allowing full chest recoil to maximize the effectiveness of each compression.

Question 4

What is the best method to give chest compressions to an infant with two rescuers?

Accepted Answer

Two-thumb encircling hands

Answer

The best method to give chest compressions to an infant with two rescuers is the two-thumb encircling hands technique. This method provides deeper and more consistent compressions compared to the two-finger technique. It also allows for better support of the infant's back, improving overall compression quality and blood flow.

Question 5

Which is an appropriate hand placement for CPR on a child?

Accepted Answer

Lower half of the sternum

Answer

An appropriate hand placement for CPR on a child is on the lower half of the sternum. Similar to adults, this central chest placement ensures that compressions are delivered directly over the heart. Using one or two hands, depending on the child's size, helps achieve the correct depth and effectiveness while avoiding injury.
