研究概览
简要总结
The primary goal of this study is to determine the effectiveness and safety of delivering continuous negative external pressure (cNEP) to the upper airway as a means of preventing episodes of respiratory impairment (RI) such as hypoxemia, apnea and hypoventilation associated with the use of intravenous sedation in elective colonoscopy in adult patients.

研究组 & 干预措施
active cNEP @ -45cmw
cNEP @ -45 cmw is applied to the anterior surface of the neck with a soft collar attached to a vacuum source.
干预措施: Airway Management System (AMS) (Device)
no intervention
Routine care is administered without the application of cNEP.
