The goal of this interventional study is to collect clinical and neurophysiological information to determine whether high-fidelity simulation can serve as a stress-inducing stimulus in a population of healthy residents (Emergency medicine, Anesthesia and Intensive care medicine, Paediatrics), both male and female, aged between 25 and 40 years. The main questions it aims to answer are:
1. Define in which phase of the simulation the highest level of stress is observed.
2. Determine the level of stress reached after performing a second high-fidelity simulation after a period of time.
3. Identify whether specific brain areas are activated during high-fidelity simulation.
Participants will form teams, consisting of three medical trainees from the same specialty training program, that will undergo two high-fidelity simulations based on a clinical scenario relevant to their residency.
* During the simulation, automatic pupillometry will be performed on all team members at the four time points.
* Additionally, a two-lead ECG will be recorded for all team members at baseline and end of the debriefing
* One team member will undergo EEG monitoring throughout the entire simulation. The EEG recordings will be sampled at baseline, during the simulation and end of the debriefing.
