From Wikipedia, the free encyclopedia
High-resolution manometry (HRM) is a gastrointestinal motility diagnostic system that measures intraluminal pressure activity in the gastrointestinal tract using a series of closely spaced pressure sensors. For a manometry system to be classified as "high-resolution" as opposed to "conventional", the pressure sensors need to be spaced at most 1 cm apart.[1][2] Two dominant pressure transduction technologies are used: solid state pressure sensors and water perfused pressure sensors.[2][3] Each pressure transduction technology has its own inherent advantages and disadvantages. HRM systems also require advanced computer hardware and software to store and analyze the manometry data.[2]
