It is the state-of-the-art approach of detect the Gastroesophageal Reflux Disease (GERD). Gastroesophageal 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.


Traditional pH recording only records acidic pH reflux episodes. Impedance-pH detects both acidic and non-acidic reflux episodes, as well as liquid, gas and mixed episodes. Combined Impedance-pH recording is clinically useful in the evaluation of symptoms under PPI therapy, as well as for hoarse-ness, unexplained cough, and applications of particular interest.


The Ohmega system is available in different configurations. For complete reflux measurement, the ambulatory Ohmega pH and Ohmega Impedance-pH recorder can be used in combination with various catheter configurations. Contact us to find the right version for you.
