Overview
To investigate the efficacy and safety of new-type mask compared with nasal tube oxygen delivery in patients undergoing sedation of upper gastrointestinal endoscopy
Description
This study aims to utilize a large sample, multicenter, prospective clinical trial using a new mask oxygen supply technology. If the study confirms that the new mask can improve the airway safety and effectiveness in patient examinations, while improving examination efficiency and reducing failure rates, it will provide safety assurance for the early diagnosis and treatment of upper gastrointestinal diseases in high-risk populations.
Eligibility
Inclusion Criteria:
- Age ≥ 18 years;
- Upcoming upper gastrointestinal sedation procedure;
- Classification under the American Association of Anesthesiologists (ASA) status I-III;
- Baseline oxygen saturation (SpO2) ≥95% in ambient air conditions.
Exclusion Criteria:
- Individuals with previously documented difficulties in mask ventilation (DMV);
- Patients predisposed to aspiration risks or episodes of vomiting;
- Facial or jaw injuries or congenital abnormalities that render conventional face mask application infeasible;
- An inability or unwillingness to utilize the novel disposable anesthesia face mask.
