The experience manometria esofagica a corporation that has already manufactured over 2, portable pH metry systems in Brazil. We cover all the brazilian territory and abroad with product specialists.
It has a proprietary probe connector, with 2 screws to secure probe connection and avoids accidental disconnection during the manometria esofagica. Records up to 8 impedance and 4 pH channels simultaneously.
Some patients exhibit exactly the required five manometria esofagica swallows to make the diagnosis. Others show consistently ineffective swallows with total absence of any normal swallow.

Abnormal reflux study was defined by excess total number of reflux episodes, abnormal esophageal acid exposure, or positive symptom association. The topographic profiles of the gastroesophageal juntion delivered by high resolution manometry HRM shows both its pressure and lowering.
The aims of this study was to describe a measurement method of the LES pressure during manometria esofagica inspiratory maneuvers with stepwise increasing efforts. The study was a qualitative and quantitative in humans.

Manometria esofagica HRM is a standard method of measuring the pressure gradient across the gastroesophageal junction and its relaxation, allowing accurate diagnosis of manometria esofagica associated with hyper or hypotonicity.
It also allows the localization of the LES upper border which is necessary for pH monitoring probe positioning 4. HRM was performed with volunteers in the supine position and after at least 6 h fasting. The probe had 36 pressure 1 cm apart and 18 impedance sensors 2 cm apart Given Imaging, Yokneam, Israel.

Pressure calibration was performed at 0 and mmHg and zeroed to atmospheric pressure before the procedure. The probe was positioned through one nostril with at least manometria esofagica sensors distal to the diaphragm. The protocol included a basal period, six 5-ml saline swallows and a respiratory maneuver 2.
