Time is on the horizontal axis and length along the esophagus on the vertical axis. Pressure magnitude is encoded in color corresponding to the scale shown at the bottom. High-pressure regions are denoted by the red end of the spectrum while the low pressure regions by the blue end. Data collected at The University Hospital, Cincinnati and plotted using MATLAB (The MathWorks Inc., Natick, MA) by Sudip K.

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] References1. ^{{cite book|last1=Brierley|first1=Stuart|last2=Costa|first2=Marcello|title=The Enteric Nervous System: 30 Years Later|date=2016|publisher=Springer|isbn=9783319275925|page=218|url=https://books.google.com/?id=fDqlDAAAQBAJ&dq=High+resolution+manometry+1cm|accessdate=18 January 2018|language=en}} 2. ^1 2 {{cite book|last1=Conklin|first1=Jeffrey|last2=Pimentel|first2=Mark|last3=Soffer|first3=Edy|title=Color Atlas of High Resolution Manometry|date=2009|publisher=Springer Science & Business Media|isbn=9780387882956|page=4|url=https://books.google.com/?id=zw4CRsJtdRgC&dq=High+resolution+manometry+1cm|accessdate=18 January 2018|language=en}} 3. ^{{cite book|last1=Bredenoord|first1=Albert J.|last2=Smout|first2=André|last3=Tack|first3=Jan|title=A Guide to Gastrointestinal Motility Disorders|date=2016|publisher=Springer|isbn=9783319269382|page=17|url=https://books.google.com/?id=GspyCwAAQBAJ&dq=High+resolution+manometry+1cm|accessdate=18 January 2018|language=en}} External links
