The main objective of this study is to determine if the use of transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) can reduce by 90 seconds the time between the entry into the operating room of the volunteer and the moment when the anaesthetic drugs are ready and when the Oxygen Reserve Index has reached a plateau value for more than 10 seconds, a moment which would therefore allow the induction of general anaesthesia, compared to the pre-oxygenation with the face mask applied by the anaesthetist alone in charge of anaesthesia.

the face mask is held by the anaesthetist (reference technique) to obtain effective pre-oxygenation for Oxygen Reserve Index (ORI) which has reached a plateau value for more than 10 seconds. All the usual supplies and medicines are available and in the same place as usual. The sequence is as follows: 1. Patient lying on the operating table, start of the stopwatch 2. Opening of the computerized anaesthesia file 3. Monitoring (ECG, non-invasive blood pressure, SaO2) of the patient 4. Preparation of the hypnotic (propofol or thiopental, as desired) 5. Preparation of curare (succinylcholine or rocuronium, as desired) 6. Pre-oxygenation of the patient with the face mask held by the participating anaesthetist 7. Waiting for an ORI which has reached a plateau value for more than 10 seconds 8. Conditions for general anaesthesia met for the participating anaesthetist 9. "End of simulation", stopwatch stop

time between when the volunteer enters the operating room and when the conditions for general anesthesia are met during pre-oxygenation
Difference between the time when volunteer enters the operating room and the time when the conditions for general anaesthesia are met during pre-oxygenation with the face mask applied by one anaesthesist in charge of the volunteer (simulated patient) compared to the use of preoxygenation with THRIVE by one anaesthesist in charge of the volunteer
Time frame: through study completion, an average of 1 year
time between volunteer enters the operating room and when the conditions for general anaesthesia are met during pre-oxygenation
Difference between the time when volunteer enters the operating room and the time when the conditions for general anaesthesia are met during pre-oxygenation with the face mask applied by one anaesthetist in charge of the volunteer (simulated patient), during pre-oxygenation with the face mask applied by the volunteer (one anaesthetist in charge of the simulated patient), during preoxygenation with THRIVE (one anaesthetist in charge of the simulated patient), during preoxygenation with the facemask applied by the anaesthetist or the nurse anaesthetist both in charge of the simulated patient
Time frame: through study completion, an average of 1 year
number of medication errors during the preparation
Medication errors occurring during treatment in the 4 scenarios will be counted (medication preparation errors, no medication is administered to the volunteer)
Time frame: through study completion, an average of 1 year
number of deviations from appropriate anaesthetic practices observed during preparation
The number of deviations from the appropriate anesthetic practices observed during the preparation will be counted in the 4 scenarios
