Usefulness of High-flow Oxygen Therapy of Patients at Risk of Hypoxemia Undergoing Digestive Endoscopy Under Deep Sedation

The study investigates the use of high-flow oxygen therapy devices in patients at higher risk of complications during sedated digestive endoscopies. Sedation controlled by the endoscopist improves patient tolerance and facilitates higher-quality procedures, but it can have side effects such as hypoxemia or respiratory depression, especially in patients with sleep apnea, obesity, lung diseases, those over 60 years old, or with a history of sedation complications. While preventive measures, such as oxygen administration, are taken, the study aims to compare the effectiveness of new high-flow oxygen therapy devices with conventional nasal cannulas to improve safety during endoscopies.
