 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 hardware and software facilities as
described below:-
Hardware/Software
requirements
The
NR6 will work with any PC running Windows
2000,XP or Vista
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.
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, r-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,
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 executive model, which
allows "raw" data
in a number of formats to be
provided
for statistical analysis and other purposes.
Capability to be called from a patient database and return values
to the database.
A Rhinocal unit,
which allows the calibration of the NR6 to be checked.

Additional
Options
A compatible Acoustic Rhinometer, the

NARIS
software. This provides rhinometric
and
rhinomanometric
measurements, with mixed results saved to a
subject database or output to a common report.
A USB footswitch, with which to initiate a measurement, can
also be supplied.
