摘要:
A system and method diagnoses esophageal reflux in a patient. A catheter includes a first pressure sensor configured to measure intra-abdominal pressure when the catheter is inserted into the stomach of a patient. A second pressure sensor is located proximal to the distal tip and configured to measure intra-thoracic pressure. A pH indicator is carried by the catheter body and configured to indicate that reflux has occurred in response to an involuntary reflex cough test. A processing device is configured to receive data regarding the first and second pressure sensors and regarding the pH indicator and process that data and assess if reflux is present during the involuntary epoch.
