Which actions are true when giving chest compressions?

Pushing rhythmically at a rate of 100-120 compressions per minute is a critical aspect of effective chest compressions during CPR. This specified range is based on research and guidelines that indicate this frequency is optimal for maintaining blood flow to the brain and other vital organs during cardiac arrest. It ensures that the heart is being adequately stimulated, enhancing the chances of survival until emergency medical services arrive.

Maintaining this rhythm is not just about the speed, but it also helps establish a pattern that can be more easily followed, especially when multiple rescuers are involved. This consistent rate supports the goal of delivering effective compressions that can produce significant circulation, contrasted with incorrect methods that may fail to optimize blood flow.

The other options do not align with best practices for performing chest compressions. For instance, positioning a guest on a soft surface may decrease the effectiveness of the compressions, while using minimal force or compressing only on the upper left chest does not provide the adequate pressure and location necessary for proper cardiopulmonary resuscitation.
