About

The need to educate healthcare practitioners was identified after an extensive demand from several providers for Dr. Davidson to individually educate them on the proper testing technique, the understanding of the readings, the interpretation of the measurement values, and how to approach patient care from an interdisciplinary approach.


After 5.5 years of extensive research, literature reviews, and clinical use of the 3 measurement technologies; rhinomanometry, acoustic rhinometry, and PNIF, DAFNE Scoring System© was created by Dr. Karen Parker Davidson, RN; Vice President of GM Instruments and a university professor.


A recent systematic review further validates the DAFNE Scoring System© and the importance of incorporating it into daily clinical practice.


In a world of digital health technology, this patent pending user interface meets the global demand for better understanding of the nasal measurement technologies, the measurement data output, and how to collaborate with other healthcare providers for better patient outcomes.
