Liquid gastric-emptying measurement using an electrical bio-impedance method / 中国医疗器械杂志

ABSTRACT

This paper introduces a 4-electrode gastric-emptying measurement system using an electrical bio-impedance method by which gastric-emptying experiments of 24 healthy volunteers have been carried out. The test results show that the base impedance is stable, the average GET/2 is 8.78 +/- 1.76 min. The new system provides a new non-invasive measurement method for the clinical study on gastric-emptying functions.
