What should be done immediately after calling for emergency help during a CPR scenario?

Beginning CPR without delay is crucial in a cardiac arrest scenario because the chances of survival decrease significantly with each passing minute that the heart is not actively pumping blood. When a child is unresponsive and not breathing, calling for emergency help is essential, but it must be accompanied by immediate action to provide the necessary circulatory support to the child's body.

CPR involves chest compressions that help to maintain blood flow to vital organs, particularly the brain and heart. The emphasis on starting CPR right away is based on the understanding that while waiting for responders can seem necessary, the likelihood of a successful outcome is much higher if intervention is initiated quickly.

Other actions such as waiting for help, checking the child's pulse, or providing rescue breaths only do not provide the immediate circulatory support that is needed in such critical situations. Waiting can lead to a further decrease in the chances of recovery as brain damage can occur within minutes due to lack of oxygen. Therefore, starting CPR promptly after calling for emergency assistance is the most effective way to increase the likelihood of survival and recovery for a child experiencing a medical emergency.
