How can you tell if a victim requires CPR?

A victim requires CPR when they are unresponsive and not breathing or only gasping because this indicates that their heart may not be effectively pumping blood to the brain and other vital organs. The absence of normal breathing or the presence of agonal gasps—brief, irregular gasps—suggests a critical lack of oxygen, signaling the need for immediate intervention.

Performing CPR in such situations serves to manually circulate blood and maintain oxygenation to the brain, significantly increasing the chances of survival until professional emergency help arrives. The prompt recognition of these signs ensures that swift action can be taken to address a potentially life-threatening condition.
