Association of Gastroesophageal Reflux and O2 Desaturation: A Novel Study of Simultaneous 24-h MII–pH and Continuous Pulse Oximetry

摘要

Proof of the relationship between gastroesophageal reflux disease (GERD) and respiratory symptoms remains a challenge. Our aim was to determine the association between reflux events and O2 desaturation in GERD patients with primary respiratory symptoms (RS) compared to those with primary esophageal symptoms (ES) using ambulatory monitoring systems.
