Dx–pH Measurement System

The Dx–pH Measurement System is a revolutionary system that comfortably measures pH in the airway. Until now it has been difficult to detect reflux in the airway because available pH catheters were developed to measure liquid reflux in the esophagus.

Gastric reflux in the airway, or supraesophageal reflux, commonly takes a gaseous form that cannot easily be measured using conventional technology. The miniaturized pH sensor at the tip of the Dx–pH Probe is the only sensor able to measure pH in the airway.

By measuring pH levels in the airway, the Dx–System is a valuable tool to assist physicians in determining the existence of laryngopharyngeal reflux and its relationship to various patient symptoms.
