Description
NR6 Clinical / Research Rhinomanometer
The NR6 Clinical / Research Rhinomanometer is designed for active anterior or posterior rhinomanometry using either the Broms or Standard technique, as approved by the International Standardization Committee.
The system displays resulting rhinomanometry curves in the standard four-phase format and can calculate and display either Rohrer coefficients or the Broms angle associated with the measured curves.
Clinical and Clinical/Research Versions
Two versions of the NR6 rhinomanometer are available: the NR6 Clinical and the NR6 Clinical/Research. The primary differences are the hardware and software capabilities included with each version.
See: Holström (2010), Rhinology, 48:387-393.
NR6 Clinical Version Features
- An individual patient database that stores patient details and test result files in chronological order for easy display, printout, and comparison.
- Test files can be saved and recalled for comparison, re-examination, or printing.
- Tests can be performed using multiple rhinomanometry techniques and reassessed by changing reference or threshold points.
- Current test results can be compared with previously stored results using graphical overlays and percentage change figures.
- A diagnostic facility helps assess whether nasal valve collapse may have occurred by evaluating flow at multiple points on the curve and calculating ratios and percentage increases.
- Software guidance based on published work assists with categorizing nasal obstruction and supporting comparative clinical study.
