Understanding Compression Techniques

Front

What is the primary benefit of performing compression-only CPR?

Back

It increases the chance of survival by maintaining blood flow to vital organs.

Answer explanation

The primary benefit of performing compression-only CPR is that it increases the chance of survival by maintaining blood flow to vital organs, which is crucial during a cardiac arrest.

Front

Which of the following is a basic step in performing compression-only CPR?
Options:
Checking for a pulse before starting compressions.
Performing chest compressions at a rate of 100 to 120 per minute.
Giving two rescue breaths after every 30 compressions.
Using an AED before starting compressions.

Back

Performing chest compressions at a rate of 100 to 120 per minute.

Answer explanation

The correct step in compression-only CPR is performing chest compressions at a rate of 100 to 120 per minute. Checking for a pulse, giving rescue breaths, and using an AED are not part of this method.

Front

What is the recommended depth for chest compressions in adults during compression-only CPR?

Back

2 inches

Answer explanation

The recommended depth for chest compressions in adults during compression-only CPR is 2 inches. This depth ensures effective blood circulation during cardiac arrest.

Front

Which of the following statements is true about the benefits of compression-only CPR? It is less effective than traditional CPR in all cases., It can be performed by bystanders without formal training., It requires specialized equipment to be effective., It is only recommended for children under 12 years old.

Back

It can be performed by bystanders without formal training.

Answer explanation

Compression-only CPR can be performed by bystanders without formal training, making it accessible and effective in emergencies. The other statements are incorrect as they misrepresent the nature and applicability of this technique.

Front

What is the main goal of chest compressions in CPR?

Back

To maintain blood circulation.

Answer explanation

The main goal of chest compressions in CPR is to maintain blood circulation. This helps deliver oxygen to vital organs until normal heart function is restored, rather than restarting the heart directly.

Front

Which of the following is NOT a benefit of compression-only CPR?
Options:
It simplifies the CPR process for untrained bystanders.
It reduces the time taken to initiate CPR.
It ensures oxygen is delivered to the lungs.
It increases the likelihood of bystander intervention.

Back

It ensures oxygen is delivered to the lungs.

Answer explanation

The correct choice is 'It ensures oxygen is delivered to the lungs.' Compression-only CPR focuses on chest compressions, which do not provide oxygen, making this statement inaccurate.

Front

What is the correct hand placement for performing chest compressions in CPR?

Back

On the lower half of the sternum.

Answer explanation

The correct hand placement for chest compressions in CPR is on the lower half of the sternum. This position allows for effective compressions to circulate blood during cardiac arrest.

Front

How does compression-only CPR benefit the victim compared to no intervention?

Back

It maintains partial blood flow to the brain and heart.

Answer explanation

Compression-only CPR helps maintain partial blood flow to the brain and heart, which is crucial for survival, compared to no intervention where blood flow ceases, leading to brain damage and death.

Front

What is the recommended position of the rescuer's arms during chest compressions?

Back

Straight and locked at the elbows.

Answer explanation

The correct position for the rescuer's arms during chest compressions is straight and locked at the elbows. This ensures maximum force is applied to the chest, allowing for effective compressions and better blood circulation.

Front

Which of the following is a key component of effective chest compressions?
Options:
Compressing at a rate of 50 per minute.
Allowing full chest recoil between compressions.
Performing compressions with one hand.
Compressing only the upper chest.

Back

Allowing full chest recoil between compressions.

Answer explanation

Allowing full chest recoil between compressions is crucial for effective chest compressions, as it helps maintain blood flow and allows the heart to refill with blood. Other options do not support effective CPR.
