Cardiopulmonary resuscitation (CPR) is a vital, life-saving technique used in emergencies when someone’s breathing or heartbeat has stopped. Performing CPR can double or even triple a person’s chances of survival after cardiac arrest. It involves chest compressions and rescue breaths to maintain blood flow to the brain and other vital organs until professional medical help arrives. Learning CPR equips you with the skills to respond effectively in critical situations, making a significant difference in the survival and recovery of individuals experiencing cardiac emergencies.
