CPR Techniques & Procedures Flashcards

When performing CPR on an adult, what is the correct hand placement for chest compressions?

Answer: On the lower half of the sternum

Compressions should be delivered to the lower half of the sternum (breastbone) to effectively compress the heart.

What is the recommended compression-to-ventilation ratio for a lone rescuer performing CPR on a child?

Answer: 30:2

A lone rescuer uses 30:2 for children, the same ratio as for adults, to simplify training.

During CPR, which of the following best describes 'full chest recoil'?

Answer: Allowing the chest to fully rise between compressions

Full chest recoil means allowing the chest to completely return to its normal position after each compression so the heart can refill with blood.

A rescuer notices they are delivering rescue breaths too quickly. What is the most likely consequence?

Answer: Gastric inflation and risk of aspiration

Breaths delivered too quickly or forcefully cause air to enter the stomach, leading to gastric inflation and risk of vomiting and aspiration.

In a two-rescuer adult CPR scenario, when should the compressor role be switched?

Answer: Every 2 minutes or 5 cycles

Rescuers should switch the compressor role every 2 minutes (approximately 5 cycles of 30:2) to prevent fatigue and maintain compression quality.

What is the correct head-tilt chin-lift technique used for?

Answer: Opening the airway by moving the tongue away from the throat

Head-tilt chin-lift opens the airway by extending the neck and lifting the chin, which moves the tongue away from the back of the throat.

Which sign indicates that a rescue breath was delivered effectively?

Answer: Visible chest rise

Visible chest rise confirms that air entered the lungs and the breath was effective.
