Restech Dx-pH Measurement System Adopted by The Oregon Clinic

Innovative Acid Reflux Test Enables Doctors to Diagnose Patients With Greater
Accuracy, Significantly Improving Treatment
SAN DIEGO--(Business Wire)--
Today, Respiratory Technology Corporation (dba Restech) announced that The
Oregon Clinic, of Portland, Oregon, has adopted the Restech Dx-pH Measurement
System to detect acid reflux in the airway. The Restech Dx-System is utilized by
The Oregon Clinic, Gastrointestinal & Minimally Invasive Surgery Division`s
(GMIS) Foregut Program for the diagnosis and treatment of all diseases of the
upper digestive system.

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.

"The Restech Dx-System is a patient-friendly way in which to diagnose an
increasingly important clinical problem - GERD related respiratory and
pharyngeal problems," said Christy M. Dunst, M.D., Primary Investigator, The
Oregon Clinic. "Our patients are often plagued with chronic symptoms like cough,
sore throat or hoarseness that can be very difficult for their specialists to
diagnosis. Since GERD is potentially treatable, identifying it as the cause of
the problem can eventually lead to a definitive treatment. We are excited to
offer this comfortable diagnostic procedure to our patients being treated in the
GMIS Foregut Program."

Kristy Fresh, Director of Operations, The Oregon Clinic, said, "We provide our
adult patients with the latest and most advanced diagnostic testing available on
the West Coast, as well as a full line of treatment options tailored specific to
each patient`s individual needs and lifestyle. The Restech DX-System helps us to
determine the least invasive intervention to relieve patients` problems for a
variety of esophageal and digestive disorders."

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.
