What is the difference between traditional rescue and modern rescue?

Modern rescue refers to the scientific, timely, advanced and effective preliminary rescue of patients at the scene of the incident. The difference: relying on doctors - relying on the public for untimely rescue - timely, effective and simple rescue - scientific handling of the scene

Rescuers often lack basic rescue concepts and skills---the "first eyewitness" should have basic rescue concepts and skills. On-site rescuers have not been trained---the "first witness" needs formal training
