What is a key component of CPR for adults?

Chest compressions being at least 2 inches deep is essential for effective CPR in adults because this depth ensures that sufficient pressure is applied to the chest, which helps to create adequate blood flow to vital organs, particularly the heart and brain. The force generated from compressions at this depth allows for the heart to adequately pump blood during the cycles of compression and relaxation.

In adult CPR, the standard recommendation is to compress the chest to a depth of at least 2 inches (5 cm), while also maintaining a rate of 100 to 120 compressions per minute. This combination of rate and depth is critical for maximizing the chances of survival in a cardiac arrest situation. The correct implementation of these guidelines significantly increases the effectiveness of CPR and the likelihood of a positive outcome.
