NR6 Rhinomanometer

The NR6 calculates nasal airway resistance by measuring nasal flow and the pressure producing that flow.

REQUEST INFO

The NR6 has a number of benefits to the user:

  • Diagnostic facilities
  • Clinical and Research versions available
  • Database system with % change calculation
  • Pre/Post challenge or operative comparisons
  • Can be interfaced through a USB PC connection
  • Software for Windows XP to Windows 10 is available
  • Includes all approved techniques, including “4 quadrant high resolution”, plus active anterior, posterior, standard and Broms angle, resistance values, plus the new Vertex and Effective resistance values, in the research version

The NR6 calculates nasal airway resistance by measuring nasal flow and the pressure producing that flow.

NR6 can be used for active anterior or posterior rhinomanometry, with either the Broms or standard technique as approved by the International Standardisation Committee. The resultant curves are displayed in the standard 4 phase format. In addition it will calculate and display either the Rohrer coefficients or the Broms angle relating to the resultant curves.

Two versions of the instruments are available,­ the NR6 Clinical and the NR6 Clinical/Research the difference between them being the hardware and software facilities.

Both NR6 models provide:

  • An individual patient database, which holds patient details and stores test result files, in chronological order, for ease of display, printout and comparison.
  • Files can be saved to disk and recalled for comparison, re-examination or printout.
  • Tests can be performed using one of a number of techniques and reassessed by changing the reference or threshold points.
  • Test results can be compared with ones previously stored. This comparison is presented in the form of a graphical display with percentage change figures produced, and is available for printout.
  • A diagnostic facility, to help determine if nasal valve collapse has occurred, has been added to the standard system. This provides information on the flow at various points on the curve and calculates ratios and percentage increases at these points.

The NR6 Clinical/Research model provides all the above features and additionally provides:

  • Flow and pressure curves displayed in a y/t format, with the calculation of Vertex and Effective resistance and their logarithmic values.
  • A batch test facility, which allows data runs to be repeated, and mean, standard deviation and coefficient of variance calculations to be displayed and printed. This “best clinical practice” facility helps ensure top grade measurement accuracy.
  • Data exportation facilities are built in to the Clinical/Research model, which allows “raw” data in a number of formats to be provided for statistical analysis and other purposes.
  • The NR6 has been successfully bi-directionally integrated with Hospital Information Systems (HIS) in various countries.
  • A Rhinocal unit, which allows the calibration of the NR6 to be checked.

Hardware/Software requirements
The NR6 will work with any PC running up to and including Windows 10, which has a USB port. Any printer with a Windows driver should be suitable.
We can supply full systems including laptops, medical grade desktop PC’s & printers or the components needed to allow you to connect the NR6 to your own PC and printer.

Additional Options
A compatible Acoustic Rhinometer, the A1 is also available, either as a free standing instrument, or linked to the NR6, making a combined unit running NARIS software. This provides rhinometric and rhinomanometric measurements, with both results saved to a subject database. A USB footswitch, with which to initiate a measurement, can also be supplied.
