The 'chain of survival' includes which of the following components?

The chain of survival is a critical concept in emergency response, particularly in situations involving cardiac arrest. One of its key components is early CPR by those first on the scene. This is essential because initiating CPR immediately can significantly increase the chances of survival for an individual experiencing cardiac arrest. CPR helps maintain blood flow to vital organs until advanced medical help can take over, increasing the likelihood of a favorable outcome.

In a scenario where a person suddenly collapses, bystanders who perform CPR right away can help sustain life until professional responders arrive. This immediate action is crucial, as every minute that passes without CPR reduces the chances of survival. By understanding the importance of early CPR, individuals can be better prepared to act decisively in emergency situations, contributing to the overall effectiveness of the chain of survival.
