Hypoxemia due to respiratory depression and airway obstruction during upper gastrointestinal endoscopy with sedation is a common concern. The Wei nasal jet tube (WNJT) is a new nasopharyngeal airway with the ability to provide supraglottic jet ventilation and oxygen insufflation via its built-in wall channel. The available evidence indicates that with a low oxygen flow, compared with nasal cannula, the WNJT does not decrease the occurrence of hypoxemia during upper gastrointestinal endoscopy with propofol sedation. To date, there has been no study assessing the performance of WNJT for supplemental oxygen during upper gastrointestinal endoscopy with sedation when a moderate oxygen flow is used.
