Summary

This trial tests whether a communication training program for emergency dispatchers can help them recognize cardiac arrest over the phone and guide callers to start CPR faster. The study involves about 987 adults who experience cardiac arrest outside of a hospital and call the SAMU-Centre 15 emergency line. The goal is to see if the training increases the number of cases where CPR instructions are given within 90 seconds, which could improve survival chances.
