Restech Dx-pH Measurement System Adopted by Seattle Children’s Hospital Cutting edge acid reflux test patient-friendly and accurate, improving diagnosis and treatment

San Diego, California, USA – March 05, 2009 – Today, Respiratory Technology Corporation (dba Restech) announced that the Division of Gastroenterology at Seattle Children’s Hospital, in Seattle, Washington, has adopted the Restech Dx-pH Measurement System™ to detect acid reflux in the airway.

Restech’s Dx-System provides valuable information about patients’ pharyngeal acid exposure and its role in various comorbidities, helping physicians diagnose the cause of each patient’s symptoms more accurately, and treat the patient more effectively.

“We are using the Restech Dx-pH system to evaluate ‘extra-esophageal’ manifestations of GERD,” said Dr. Tyler Burpee, M.D., at Seattle Children’s Hospital, specializing in pediatric acid reflux disorders. “These can include dental enamel erosions, hoarse voice, recurrent sinus infections, and chronic respiratory symptoms. The Restech Dx-pH system is great in that it gives us a valuable new tool to objectively evaluate this association. For some patients, it can really change how their symptoms are managed. It is non-invasive and well tolerated, even in our younger pediatric patients. The Dx-pH System enables us to more aggressively treat for reflux or to wean off previously started anti-reflux treatments and search for other causative factors.”


Restech Dx–pH Measurement System
The Restech Dx–pH Measurement System is a revolutionary system that comfortably measures pH in the airway. Gastric reflux in the upper airway, or laryngopharyngeal reflux, commonly takes a gaseous form that cannot be measured using conventional technology. The miniaturized pH sensor at the tip of the Dx–pH Probe is unique in its ability to measure pH in a non-liquid environment, such as the pharynx. By monitoring the pH levels in the pharynx, the Dx–System enables physicians to confirm or deny the presence of laryngopharyngeal reflux, and evaluate it as a possible contributor to their patients’ symptoms.

The Dx–pH Probe’s miniaturized, patented sensor is housed in the tear-drop shaped tip at the distal end of a thin trans-nasal catheter. An LED blinks during placement, allowing the medical personnel to confirm the proper placement in the oropharynx. The small size and minimally invasive position of the Restech Dx–pH Probe allows patients to carry on normal, everyday activities including eating, talking and sleeping with more comfort than conventional esophageal pH probes.

The measurements taken by the pH sensor are sent wirelessly to a recording device which the patient carries throughout the study period. Upon completion of the study (usually 24 hours), the patient returns to the physician’s office where the data is downloaded and presented graphically for analysis using Restech’s custom Dx–pH DataView software.
