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.

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 Compact and the NR6 Executive -the difference between them being software facilities as described below

Hardware/Software requirements

The NR6 will work with any PC running Windows 2000, NT, XP or Vista, which has room for a PCI bus card (full height), or a USB connection.  Any printer with a Windows driver should be suitable.

We can supply full systems including a medical grade PC & printer or the components needed to allow you to connect the NR6 to your own PC and printer.

Both NR6 models provide:-

a) An individual patient database, which holds patient details and stores test result files, in chronological order, for ease of display printout and comparison.

b) Files can be saved to disk and recalled for comparison, examination or printout.

c) Tests can be performed using one of a number of techniques and reassessed by changing the reference or threshold points.

d) 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.  

e) 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 Executive model additionally provides:-

All the above features plus:-

A batch test facility to allow data runs to be repeated and mean, standard deviation and coefficient of variance calculation for results within the batch to be displayed and printed. This “best clinical practice" facility helps ensure top grade measurement accuracy.

Data exportation facilities are built in to the executive model which allows  "raw" data in a number of formats to be provided for statistical analysis and other purposes.

Accessories and Consumables

Additional Options

A USB linked footswitch, to initiate sampling can be ordered separately. A compatible acoustic rhinometer model A1 can be linked to the same interface card as NR6 and can therefore share the same PC and printer. Software to run both instruments as a combined unit (Naris) and a sound tube capable of making both measurements almost simultaneously, is also available.

A calibration unit FP2 can be provided for use with the NR6.
