The NR6 calculates nasal airway resistance by measuring nasal flow and the pressure producing that flow.
Active anterior or posterior rhinomanometry, using either the Broms or standard techniques, can be performed.
The NR6 examination results are calculated using the four-phase system approved by the International Standardization Committee.
The NR6 provides an individual patient database that holds patient details and stores test result files in chronological order for ease of display on printout.
Test results can be compared with results previously stored. This comparison is presented in the form of a graphical display with percentage change figures produced.
