The Ohmega is a small and lightweight ambulatory system which combines Impedance recording and pH recording. As a result, the Ohmega detects reflux activity using Impedance and categorises these reflux episodes as acidic or non-acidic (weakly acidic), using traditional pH measurement. Gas and mixed liquid/gas reflux episodes are also analysed.
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.
Gastro-Esophageal Reflux Disease (GERD) is caused by the reflux of gastric contents into the oesophagus. 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 hoarse-ness, unexplained cough, and applications of particular interest.
