Which of the following groups greatly benefits from practicing CPR regularly?

Practicing CPR regularly is essential for anyone who might witness an emergency, as they are often the first line of response in critical situations. Sudden cardiac arrests can happen anywhere, and bystanders who know how to perform CPR can provide immediate assistance, which significantly increases the chances of survival for the victim.

Regular practice helps reinforce the skills and knowledge necessary to remain calm and act effectively in emergencies, enabling quick recognition of the need for CPR and proper execution of the technique. This preparedness is crucial because survival rates dramatically decrease with every passing minute without intervention; hence, empowering a wide range of individuals, rather than a select few, ensures a more effective response in communities.

The other groups mentioned may have some level of benefit, but they do not encompass the broad, community-oriented approach that is vital for saving lives in a public setting.
