Study population: Medical regulation assistant taking a call from a witness of a cardiac arrest between 01/01/2024 and 30t/04/2024

Brief summary: This study aims to evaluate the average time taken by the Medical Regulation Assistants (MRA) to detect a cardiac arrest during the call to the EMS as well as the factors influencing this delay.

Its main objective is to evaluate the delay, in seconds, between the call being picked up and the recognition of a cardiac arrest by the medical regulation assistant at the EMS 95

Detailed description: In France, the incidence of cardiac arrest in adults is approximately 40,000 per year. It is a major cause of mortality with an average survival rate of 8%, as well as morbidity, particularly neurological morbidity for surviving patients. The majority of cardiac arrests occur at In France, the incidence of cardiac arrest in adults is approximately 40,000 per year. It is a major cause of mortality with an average survival rate of 8%, as well as morbidity, particularly neurological morbidity for surviving patients. The majority of cardiac arrests occur at home, in the presence of a witness.

In the event of a cardiac arrest, every minute counts. Studies have shown that the time between the patient's collapse and the start of ECM (External Cardiac Massage) is directly correlated to the survival rate after a cardiac arrest.

According to other studies, a maximum delay of 90 seconds between the call to the EMS and the recognition of the cardiac arrest would be the most optimal for the patient, but is it reached at the EMS 95? This study aims at evaluating the average time taken by the Assistants of Medical Regulation (ARM) to detect a cardiac arrest during the call to the EMS as well as the factors influencing this delay.

Its main objective is to evaluate the delay, in seconds, between the call pick-up and the recognition of a cardiac arrest by the medical regulation assistant at the EMS 95. This evaluation will be made in particular by determining the elements of language highlighting the cardiac arrest, those which lengthen the time of detection of the arrest and the delay of starting a procedure by the ARM. The study will be conducted within the EMS and will include a review of the current state of knowledge and experience of the MRAs. This study will be carried out within the EMS 95.

Eligibility criteria: Inclusion Criteria :

- Any call resulting in the detection of a cardiac arrest during ARM regulation: calls to 15 and calls transmitted by 18

Exclusion Criteria :

* Traumatic context
* Call involving cardiac arrest already identified as such by the caller or 18
* Call with criteria of proven death
* The caller does not speak French, the linguistic elements noted are not usable.

Primary outcomes:
measure: Evaluation, of the time elapsed (seconds) between the taking in charge of the call and the recognition of a cardiac arrest by the medical regulation assistant (ARM) of the EMS 95.
timeFrame: At the end of the study, an average of 5 month
Secondary outcomes:
measure: Identify language that highlights cardiac arrest
timeFrame: At the end of the study, an average of 5 month
measure: Identify language that increases the time to detect cardiac arrest
timeFrame: At the end of the study, an average of 5 month
measure: Evaluation of the time required for the MRA to initiate a procedure (AED search: External Automated Defibrillator or initiation of external cardiac massage assistance)
timeFrame: At the end of the study, an average of 5 month
measure: Identification of factors that may influence the time to recognition of cardiac arrest (MRA experience, tone of the call)
timeFrame: At the end of the study, an average of 5 month
