The Central California Ear, Nose & Throat Medical Group (CCENT) has adopted Restech’s Dx-pH Measurement System to detect acid reflux in the throat. Nighttime acid reflux is associated with considerable sleep problems in patients.

The Dx-pH Measurement System utilizes a catheter that can measure pH in the airway. Until now, measuring pH in the airway was not possible because pH catheters could measure only liquid reflux in the esophagus and not the aerosolized form of stomach acid found in the larynx and throat.

“The Restech Dx-pH Measurement System allows us to easily measure stomach acid levels in the throats of patients and to correlate these levels with patient symptoms,” says Bret Sherman, Md, PhD, an otolaryngologist at CCENT. “We are now able to determine exactly when and how much stomach acid reaches the throat. This leads to significantly better health care for our patients with throat and voice problems.”

The Restech Dx-pH is also portable. The system sends measurements wirelessly to a recording device carried by patients during the 24-hour test period. The patient then returns to the center to have the recording evaluated by a physician.
