How does the Dx–pH Measurement System work?
The Dx–pH Measurement System is a simple tool for 24 to 48 hour ambulatory oropharyngeal pH testing. Guided by a blinking light-emitting diode (LED) in the probe tip, the physician visually positions the probe just behind the soft palate. Once placed, the single-channel Dx–pH Probe takes a pH reading every 1⁄2 second then sends the data wirelessly from the attached Dx–Transmitter to the Dx–Recorder. Throughout the study, the parent inputs clinically relevant information (e.g. meals, symptoms) with the push of a button. Upon completion of the study, the pH data and patient information is downloaded from the SD memory card into the Dx–pH DataView software program to be viewed, graphed and printed.
