Ohmega detects reflux activity using Impedance and categorizes these reflux episodes as acidic or non-acidic (weakly acidic), using traditional pH measurement. Gas and mixed liquid/gas reflux episodes are analyzed as well.
Traditional pH recording only records acidic pH reflux episodes. Impedance-pH detects both acidic and non-acidic reflux 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 Virtual Instructor Program™ helps to complete the procedure successfully with minimal training. Bluetooth® capabilities make it possible to view and check data on a computer monitor while recording. The intelligent symptom analysis software quantifies reflux episodes quickly and simply.
The Ohmega is available in different configurations. Contact us to find the right version for you.

Impedance-pH Reflux Measurement to assist in the Diagnosis of GERD
What is Impedance?
Impedance measurement can be used to assist in detecting GERD (Gastroesophageal Reflux Disease) and distinguish acid and weakly acidic refluxes causing symptoms.
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.
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  .
LABORIE is passionate about bringing freedom and dignity to patients suffering from gastroenterological diseases and disorders through innovation in diagnostic and treatment options. We work with leading clinician-researchers and local universities to incorporate the most recent advancements and technical knowledge into our products while reflecting practical realities of the typical GI clinic.
