For which age group should the compression depth of about 2 inches be applied during CPR?

The compression depth of about 2 inches is recommended for adults during CPR. This depth is crucial as it allows for effective circulation of blood to the heart and brain. In adults, the chest cavity is larger, and compressing to this depth ensures that there is adequate pressure to pump blood forward, especially in cases of cardiac arrest.

For infants, the recommended compression depth is about 1.5 inches, as their ribcage is much smaller and more flexible. In the case of children, specific guidelines suggest a depth that is approximately 1.5 to 2 inches, depending on their size and age, but generally less than the standard for adults. Therefore, the 2 inches compression depth aligns specifically with the adult population during CPR, ensuring that the compressions are effective in restoring circulation during life-threatening situations.
