What should untrained individuals do if they encounter a person in need of CPR?

The most appropriate action for untrained individuals encountering a person in need of CPR is to perform CPR only if instructed. While it's admirable to want to help, untrained individuals risk performing CPR incorrectly, which could potentially do more harm than good. The effectiveness of CPR hinges on proper technique, which requires training. Therefore, if untrained bystanders are present, they should call for expert assistance and seek guidance, ideally from a trained professional or through a dispatcher giving instructions over the phone.

Individuals are encouraged to take action in emergencies, as immediate assistance can save a life. However, without proper training, it's essential to engage professionally trained emergency services to ensure the best care is given. Thus, performing CPR without knowledge or instruction is not advisable as it could lead to unintended consequences for the individual requiring assistance.
