What this trial studies

This observational study aims to evaluate the efficacy and effects of self-performed preoxygenation by patients prior to undergoing general anesthesia. It focuses on patients classified as ASA Physical Status I or II, who are scheduled for surgery and can understand and speak French. The study will utilize various scales to assess anxiety and comfort levels during the preoxygenation process. By examining this patient-led approach, the study seeks to gather insights into its practicality and effectiveness in clinical settings.

Who should consider this trial

Good fit: Ideal candidates are patients undergoing scheduled surgeries with general anesthesia who are classified as ASA I or II and can communicate in French.

Not a fit: Patients with respiratory comorbidities, obesity, or cognitive impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance patient comfort and reduce preoperative anxiety during anesthesia induction.

How similar studies have performed: While the concept of preoxygenation is well-established, this specific approach of self-preoxygenation has not been extensively tested in prior studies.
