摘要：
A system and method diagnoses acid reflux. A nasogatric/orogastric (Ng/Og) device is inserted through the esophagus and into the stomach of a patient. The Ng/Og device includes a pressure sensor configured to measure intra-abdominal pressure and a plurality of pH sensors positioned along the Ng/Og device. An involuntary reflex cough epoch is induced within the patient. The intra-abdominal pressure and elevation of reflux along the Ng/Og device is measured. A subsequent step determines the functional status of the gastric valve based on the measured intra-abdominal pressure and the elevational reflux along the catheter created by the increased intra-abdominal pressure that occurs during the involuntary reflex cough epoch.
