Nasal provocation test (NPT) through previously active rhinomanometry: physical and mathematical reasons

Rhinomanometry is a technique which studies the resistance of the nasal airways. It also permits us to measure their variations during NPT. This work has analysed the different methods of rhinomanometry (previously active, previously passive and late), commenting on its advantages and disadvantages. Bearing in mind that the European Committee for the standardizing of rhinomanometry has suggested the use of AAR, we have analysed it's physical and mathematical principles, as well as the bases of NPT through AAR. On these principles we present our technique, highly standardized, showing the comparative data with other diagnostic methods, as well as it's diagnostic value and we compare it with other proposed systems. We have also considered it useful to include a mathematical development of TPN which informs us of the equations of regression for the dose and nasal responses.
