What can be the outcome of performing CPR effectively?

Performing CPR effectively significantly enhances a person's chances of survival until professional help arrives. This is particularly crucial in emergency situations where cardiac arrest occurs, as the application of CPR maintains blood circulation and oxygenation to vital organs, which can prevent irreversible damage.

While it can lead to improved outcomes, including the potential for recovery, it does not ensure a complete return to full health immediately, nor does it guarantee recovery. It also does not restore breathing on its own; rather, CPR serves as a critical stopgap measure until advanced medical assistance can take over. The primary goal is to sustain life and preserve brain function by providing essential blood flow, thus increasing the likelihood of survival until further medical intervention can be administered.
