Efficacy of Pre-oxygenation and High-Flow Nasal Oxygen during ERCP in High-risk patients with hypoxemia: A Randomized Controlled Trial

Aims Endoscopic retrograde cholangiopancreatography (ERCP), a procedure requiring deep sedation, poses an elevated risk of hypoxemia, particularly in high-risk patients. Pre-oxygenation and high-flow nasal oxygen (HFNO) have demonstrated effectiveness in improving oxygenation.
