What is essential when performing a rescue of an unconscious victim?

When performing a rescue on an unconscious victim, the most critical step is to begin CPR immediately if the victim is not breathing. This is because time is of the essence in a life-threatening situation. The absence of breathing indicates that the victim's oxygen supply is compromised, and each passing moment can significantly reduce their chances of survival.

Starting CPR helps to maintain blood circulation and can prolong the brain's access to oxygen while waiting for professional medical help to arrive. The emphasis in emergency response is on quickly restoring oxygen flow to vital organs, especially the brain. Consequently, initiating chest compressions and rescue breaths promptly is essential to improve the chances of recovery.

Other considerations, such as calling for help or checking for a pulse, are important in the overall emergency response process, but they should not delay the initiation of CPR in a situation where the victim shows no signs of breathing.
