When should you perform CPR?

You should perform CPR immediately if you find someone who is unresponsive (does not wake up or respond to you) and is not breathing normally or not breathing at all. The general public is no longer expected to check for a pulse because this can be difficult and time-consuming. Instead, if the person is unresponsive and not breathing or only gasping, you should start CPR right away. This helps maintain blood flow to the brain and vital organs, significantly increasing their chances of survival until emergency services arrive.
