Clinical Trial: High Flow Nasal Cannula and Mask Oxygenation in Patients With Visceral Obesity Undergoing Sedated Gastroscopy

U.S., Sept. 9 -- ClinicalTrials.gov registry received information related to the study (NCT07159022) titled 'High Flow Nasal Cannula and Mask Oxygenation in Patients With Visceral Obesity Undergoing Sedated Gastroscopy' on Aug. 27.

Brief Summary: During sedated gastroscopy, the insertion of the fiberscope and gastric distension required to perform the examination may induce respiratory depression, airway obstruction, and decreased chest wall compliance. Patients with obesity, especially visceral fat, have poor lung and chest wall compliance, lower lung capacity and functional residual capacity, and an unbalanced ventilation-to-perfusion ratio. Thus, obese patients are at a high risk of hypoxemia.

Increasing evidence supports the use of Hi...
