Hypoxemia
Does Capnography Prevent Hypoxemia During Endoscopic Retrograde Cholangiopancreatography and Endoscopic Ultrasound?
Subjects undergoing elective ERCP and EUS will receive standard monitoring and sedation. In addition, capnography which measures carbon dioxide levels and can graphically assess respiratory activity will be used.
