Yes, the Dx–pH Probe can record liquid pH in the esophagus as well as aerosolized pH in the oropharynx. The placement of the Probe in the oropharynx, posterior to the uvula, seems to be the most comfortable location for the patient and the clinical results from this location accurately display supraesophageal pH levels attributable to gastric reflux events. Positioning the Probe in the lower pharyngeal area is possible, although not recommended because of possible patient discomfort.

The placement of the Probe in the oropharynx, posterior to the uvula, seems to be the most comfortable location for children and the clinical results from this location accurately display laryngopharyngeal pH levels attributable to gastric reflux events. Positioning the Probe in the lower pharyngeal area is possible, although not recommended because of possible patient discomfort.
