Impedance-pH reflux measurement to diagnose GERD
|Select your country:||> USA|
What is Impedance?Impedance measurement can be used to detect GERD (Gastro Esophageal Reflux Disease) and distinguish acid and weakly acidic refluxes causing symptoms.
Gastro-Esophageal Reflux Disease (GERD) is caused by the reflux of gastric contents into the esophagus. Typical patient symptoms are heartburn, regurgitation, and chest pain. These patient groups are often on PPI medication, but non-acidic reflux can still cause symptoms.
Combined Impedance-pH recording is clinically useful in the evaluation of symptoms under PPI therapy, as well as for hoarseness, unexplained cough, and applications of particular interest.
