The goal of this clinical trial is to learn if the use of virtual reality immersion during pre-oxygenation before general anesthesia could be feasible and beneficial for the patient. The main questions it aims to answer are: Does virtual reality immersion during pre-oxygenation reduce patient's anxiety? Does it impact patient's and anaesthetist's comfort? Is this technique easy to implement?

Patient's Anxiety during pre-oxygenation
Anxiety will be assessed with the Visual Analogue Scale for Anxiety (VASA) scale ranging from 0 to 10 (0 corresponds to the lowest level of anxiety and 10 to maximal level of anxiety).
Time frame: 4 min after the beginning of pre-oxygenation.
Change in patient's anxiety over time
Change in Visual Analogue Scale for anxiety (VASA) between 4 time points. VASA scale ranges from 0 to 10 with 10 corresponding to the highest level of anxiety.
Time frame: The four time points are: in the ward on the day of surgery, in the theater once the patient is monitored and before pre-oxygenation, 4 min after the beginning of pre-oxygenation, in the ward at least two hours after the end of surgery.
Success rate in recruiting patients to participate to the study
Rate of patients accepting to participate to the study. The number of patients accepting to participate will be descrided in percent (%) with the denominator beeing the sum of patients who accepted and refused to participate to the study.
Time frame: During study recruitment.
Completed pre-oxygenation with virtual reality headset
Rate of patient who completed pre-oxygenation with the virtual reality headset. The rate of patient who completed the pre-oxygenation with the virtual reality headset will be measured in percent (%).
Time frame: From the beginning to the end of the pre-oxygenation period.
Anxiety evaluation with the Amsterdam Preoperative Anxiety and Information scale (APAIS) score
The APAIS score is a validated score to evaluate anxiety in the preoperative context. It ranges from 6 to 30 with the highest score corresponding to a high level of anxiety.
Time frame: At two times: on the day of surgery while the patient is still in the ward and after entry in the OR up to the beginning of pre-oxygenation.

Change in blood pressure over time
Variation of blood pressure (systolic arterial pressure, diastolic arterial pressure, mean arterial pressure) between four time points.
Time frame: The four time points are: in the ward on the day of surgery, the first blood pressure measured in theater, at the beginning of the pre-oxygenation and at the end of the pre-oxygenation (just before the beginning of the general anaesthesia induction)
Change in oxygen saturation over time
Variation of oxygen saturation measured with finger pulsoxymeter between four time points.
Time frame: The four time points are: in the ward on the day of surgery, the first oxygen saturation measured in theater, at the beginning of the pre-oxygenation and at the end of the pre-oxygenation (just before the beginning of the general anaesthesia induction)
Change in heart rate over time
Variation of heart rate measured between four time points.
Time frame: The four time points are: in the ward on the day of surgery, the first heart rate measured in theater, at the beginning of the pre-oxygenation and at the end of the pre-oxygenation (just before the beginning of the general anaesthesia induction)
Patient's comfort during pre-oxygenation
Patient will be asked it's level of comfort during pre-oxygenation with a Likert scale ranging from 0 to 10 (with 0 corresponding to the maximum comfort and 10 to the minimal comfort).
Time frame: During pre-oxygenation (at 2 minutes after pre-oxygenation initiation).
Incidence of cybersickness
Incidence of cybersickness during the pre-oxygenation period in percent (%).
Time frame: From the beginning to the end of the pre-oxygenation period.
Comfort of the anesthetic team during pre-oxygenation
Evaluation of the involved anesthetic team comfort regarding the pre-oxygenation technique with a Likert scale ranging from 1 to 5 (1 corresponding to the lowest level of comfort and 5 to the highest level of comfort).
Time frame: From the beginning to the end of the pre-oxygenation period.
Perceived comfort of the patient during pre-oxygenation
Perceived comfort of the patient during pre-oxygenation by the involved anesthetist team with a Likert scale ranging from 1 to 5 (1 beeing the lowest level of comfort and 5 beeing the highest level of comfort).
Time frame: From the beginning to the end of the pre-oxygenation period.
Wake up quality test
Wake up quality test with a 3-point scale (good, satisfactory, poor).
Time frame: From the beginning of the awakening after general anesthesia to the removal of the airway device.
Patient's satisfaction regarding the pre-oxygenation period
Evaluation of patient's satisfaction regarding the pre-oxygenation technique with a 5-point Likert scale (1 beeing the lowest level of satisfaction and 5 the highest level of satisfaction)
Time frame: From 2 hours after the end of anesthesia to the first day after surgery.
Qualitative post-operative survey regarding patient's experience during pre-oxygenation
Qualitative post-operative survey with questions about patient's experience during pre-oxygenation.
Time frame: From 2 hours after the end of anesthesia to the first day after surgery.
