Gastroscan-IAMImpedance-pH-monitor Gastroscan®-IAM
Impedance-pH-monitor (Impedanceacidomonitor) Gastroscan-IAM is designed for the multichannel simultaneously measures the intraluminal impedance and acidity in a gastrointestinal tract for the study of both acid and nonacid gastroesophageal reflux. Russian specification of the Gastroscan-IAM is ИАМ-01, ТУ 9442-011-13306657-2011.
The impedance-pH monitoring diagnostic test determines the frequency of reflux episodes and the time relationship of reflux episodes and symptoms. The impedance-pH monitoring test determines if the patient's symptoms are related to acid reflux, related to nonacid reflux, or not related to reflux of any type. A positive GERD diagnosis is made if acid or nonacid reflux precedes symptoms in a statistically meaningful manner.

  • measures the intraluminal impedance of the 7 canneles

  • simultaneously measures the acidity in three locations of a gastrointestinal tract in the range from 1.1 to 9.2 pH in 24 hours; the time interval between measurements is 1 sec.

  • detects both acid and nonacid bolus movement and acid and nonacid gastroesophageal reflux.

  • provides registration of the patient and his actions with the keyboard located on the front panel

  • current results of impedance and pH measurements can be displayed directly recording unit during the study

  • handles the information stored on your computer

  • displays information about the state of the upper gastrointestinal tract Z-pH-probe for impedance-pH-metry

  • saves the results of a study in the database

  • reveals the pathology of the gastrointestinal tract and individual choice of drug therapy

Z-pH-catheters for impedance-pH-metry

The Istok-Sistema has developed and manufactures special Z-pH-catheters for simultaneous measurements of impedance and acidity in the gastrointestinal tract. Such Z-pH-catheters may contain a different number of electrodes for impedance measurements and pH electrodes depending on the wishes of the customer.

Gastroscan-IAM allows you to define different types of reflux

Combined impedance-pH recordings allows to identify the three types of reflux (Kaibysheva V., Trukhmanov A., Ivashkin V.):
  • Liquid acid reflux: retrograde drop in impedance starting distally together with a pH fall below 4 a)

  • Liquid weakly acidic reflux: retrograde drop in impedance starting distally together with a pH fall below 7 but above 4 (fig. b)

  • Liquid alkaline reflux: retrograde drop in impedance starting distally with pH values above 7 (fig. c)
