Question

How can you achieve a high chest compression fraction?

1) By performing chest compressions at the correct depth
2) By ensuring full chest recoil between compressions
3) By maintaining a compression rate of 100-120 compressions per minute
4) All of the above

Answer 1

To achieve a high chest compression fraction in CPR, performing chest compressions at the correct depth, ensuring full chest recoil between compressions, and maintaining a compression rate of 100-120 compressions per minute are all essential. Thus, the answer is 4) All of the above.

Step-by-step explanation:

To achieve a high chest compression fraction during CPR, all the listed factors contribute to its effectiveness. A high chest compression fraction can be achieved by:

• Performing chest compressions at the correct depth of at least 5 cm.
• Ensuring full chest recoil between compressions to allow the heart to refill with blood.
• Maintaining a compression rate of 100-120 compressions per minute.

Therefore, the correct answer to the question is 4) All of the above. It's important to combine the correct depth and rate with allowing complete chest recoil to ensure the highest possible efficacy of CPR.
