to determine whether this was true and to characterize the effects of changes in r0 in the range of normal nasal resistance ( rn ) , we determined r0 and delta r50 using standard techniques under the following conditions : nose vs. decongested nose , nose vs. nose with added external r0 ( 3.0 and 8.0 cmh2o x l-1 x s ) , nose vs. anesthetized nose , nose vs. mouth , and mouth vs. mouth with added load ( 3 cmh2o x l-1 x s ) .
