What distinguishes CPR from standard first aid procedures?

CPR, or cardiopulmonary resuscitation, is specifically designed to address life-threatening emergencies, particularly in cases of cardiac arrest or respiratory failure. The key distinction of CPR lies in the methodology involving chest compressions and rescue breaths. This technique aims to manually circulate blood and provide oxygen to the brain and other vital organs when the heart has stopped beating or when a person's breathing has ceased.

In comparison, standard first aid procedures typically address less critical situations such as minor injuries (like cuts and bruises) and do not involve the intensive intervention required in CPR. Standard first aid may include wound care, bandaging, or the administration of basic support until professional help arrives, but it does not involve life-saving techniques like chest compressions and rescue breaths.

Special equipment is often not necessary for effective CPR—while there are devices that can assist in the process, basic CPR can be performed using just one’s hands and mouth. Additionally, although anyone can be trained to perform CPR, it is not restricted to medical professionals; bystanders are often encouraged to intervene in emergencies. Thus, the core distinction of CPR lies in its focus on preserving life through distinct actions, which clearly sets it apart from standard first aid practices.
