Project Description


Patients on PPI’s who continue to experience symptoms such as cough, heartburn, regurgitation and chest pain often are difficult to diagnose using traditional acid (pH) monitoring approaches.

The ZepHr® Impedance/pH Reflux Monitoring System employs impedance to detect ALL reflux activity and uses pH to categorize each episode as acid or nonacid for Total Reflux Monitoring. Comprehensive analysis quantifies all reflux patterns and symptom associations in patients studied on or off acid suppression medication.
