Cognitive failure under multitasking conditions has been demonstrated in various settings, including healthcare. However, in anesthesiology, the impact of multitasking on clinical performance has not yet been fully characterized.
The objective of our study is to evaluate the impact of multitasking on anesthesiologists' clinical performance in a simulated setting.

Multitasking
Other interventionSimulation training session during which participants will be required to multitask by performing manual mask ventilation on a manikin while answering oral clinical questions administered in the form of Script Concordance Tests (SCTs).
Concordance score with the expert panel on a Script Concordance Test (SCT)
Each item of the SCT is scored out of 1 point, and the sum of the points, converted to a 100-point scale, defines the percentage of concordance with the expert panel.
Manual ventilation performance assessed by variance of expiratory tidal volume (ml)
Participants will be instructed to ventilate with an expiratory tidal volume (Vte) between 450 and 500 mL at a respiratory rate of 15 breaths per minute. Variability in Vte will be used as an indicator of the difficulty in complying with these instructions.
Manual ventilation performance assessed by variance of respiratory rate (cycles/minute)
Participants will be instructed to ventilate with an expiratory tidal volume (Vte) between 450 and 500 mL at a respiratory rate of 15 breaths per minute. Variability in respiratory rate will be used as an indicator of the difficulty in complying with these instructions.
Cognitive load assessed by the NASA-TLX index (score out of 100)
The Official NASA Task Load Index (TLX) is a subjective workload assessment tool. By incorporating a multi-dimensional rating procedure, NASA TLX derives an overall workload score based on a weighted average of ratings on six subscales: mental demand, physical demand, temporal demand, performance, effort, frustration.
Time to answer items of the script concordance test (seconds)
Time between end of question and beggining of answer for each item of the script concordance test. Evaluates the interruption lag.
Exploratory sub-group analysis of the primary outcome measure
Subgroups: * Clinical experience in anesthesiology \< or \>= 5 semesters * Left handed or right handed * Musical practice \< or \>= 5 years * Need for cognition scale (18 questions): \< or \>= median of the group score
Exploratory subgroup analyses of expiratory tidal volume variance and respiratory rate variance
Subgroups: * Clinical experience in anesthesiology \< or \>= 5 semesters * Left handed or right handed * Musical practice \< or \>= 5 years * Need for cognition scale (18 questions): \< or \>= median of the group score
Descriptive analysis of ventilation parameters
* Inspiratory tidal volume (ml) * Expiratory tidal volume (ml) * Respiratory rate (cycles/minute) * Resumption lag: time required to re-establish stable ventilation following interruption (seconds)
