Therefore, its use during endoscopic procedures with intravenous deep sedation may help maintain airway patency and oxygenation. This study aims to compare the incidence of reductions in oxygen saturation in subjects receiving HFNC at different flows with that in subjects receiving conventional oxygen therapy during endoscopic retrograde cholangiopancreatography (ERCP).
