To ensure effective CPR, what is critical regarding chest compressions?

Compressions should not allow any recoil
Compression depth should be at least 2 inches
Use one hand for compression
Avoid any communication during CPR

The correct answer is: Compression depth should be at least 2 inches

The correct answer emphasizes the importance of compression depth during CPR. For adult victims, it is essential that chest compressions are performed at a depth of at least 2 inches while allowing for full chest recoil between compressions. Adequate compression depth is necessary to create sufficient blood flow to vital organs; if compressions are too shallow, the effectiveness of CPR is compromised, potentially leading to worse outcomes. Utilizing the proper compression depth ensures that enough pressure is applied to the chest to circulate blood effectively without causing injury. Full recoil allows the heart to fill adequately between compressions, which is vital for optimal circulation. Thus, adhering to the guideline of a compression depth of at least 2 inches is crucial to maintaining the effectiveness of CPR.
