What is an important step to ensure effectiveness when performing CPR?

Ensuring a proper compression depth is crucial for the effectiveness of CPR because it directly influences the chances of delivering adequate blood flow to vital organs, especially the heart and brain. When performing chest compressions, the depth should typically be about 1.5 to 2 inches for infants and about 2 inches for children. This depth is necessary to create enough pressure in the chest cavity, which facilitates the pumping of blood during each compression. If the compressions are too shallow, the blood may not flow effectively, which reduces the chances of reviving the victim.

The other steps, while they may seem relevant in certain contexts, do not contribute as directly to the success of CPR. For instance, frequently checking the time can be distracting and might lead to interruptions in compressions. Maintaining a conversation with the victim is generally not feasible in a CPR scenario, as the person is often unresponsive. Additionally, giving frequent breaks during CPR can lead to decreased blood flow and is discouraged unless absolutely necessary, such as during a transition to advanced care. Therefore, focusing on the proper compression depth is paramount to ensure that CPR is performed effectively.
