What should bystanders do while CPR is being performed?

The correct action for bystanders while CPR is being performed is to help call for emergency assistance and bring an AED if available. This is critical because CPR alone may not be sufficient for effective resuscitation in some cases, and the use of an AED significantly increases the chances of survival in cases of cardiac arrest.

When bystanders engage in helping to call for emergency services, they ensure that professional medical personnel are on the way as quickly as possible. Additionally, if they can retrieve an AED, this device can provide lifesaving electric shocks to restore a normal heart rhythm, working in conjunction with CPR. This coordinated effort maximizes the victim's chances of survival until advanced medical help arrives.

While it may seem tempting for bystanders to watch quietly, this passivity does not contribute to the emergency response and could unnecessarily prolong the time before professional aid arrives. Similarly, it’s important that bystanders do not self-initiate CPR if it’s already being performed by someone trained, as this can disrupt the efforts. Finally, leaving the scene can exacerbate the situation by removing vital support and assistance that could be rendered. Hence, bystanders should actively participate by calling for help and securing an AED if feasible.
