What should you shout to attract assistance when performing CPR?

When performing CPR, it is crucial to attract attention effectively to ensure prompt assistance from others nearby. Shouting "Help, help!" is particularly impactful because it is a clear and urgent call for assistance that emphasizes the need for immediate support. The repetition of the word "help" conveys a sense of emergency, making it more likely that those who hear it will respond quickly and provide the necessary aid or call for emergency services.

Using a phrase like "Help me!" can be effective, but it might not carry the same urgency or clarity of needing immediate assistance as the repeated call for "help." Similarly, "Call 911!" while certainly a necessary action, does not engage bystanders in the same way. "Somebody assist!" may be less direct than the other options and may not immediately resonate as a call for urgent support.

In an emergency situation, clarity and urgency can greatly increase the chances of getting the help needed in a timely manner, thus making "Help, help!" an appropriate choice in calling for assistance while performing CPR.
