Geographic Locations of Nasal Airflow Research in the USA
The provided evidence does not specify particular geographic locations, cities, or institutions within the United States where nasal airflow studies are conducted. The guideline and research documents focus on methodological approaches and technical standards for measuring nasal airflow rather than identifying specific research centers or laboratories 1.
What the Evidence Does Reveal
The literature describes standardized measurement techniques and computational approaches used internationally, but does not delineate U.S.-specific research sites 1.
Key Research Methodologies Employed:
Nasal probe development for measuring temperature and humidity at the nasal inlet and nasopharynx, with sensors positioned to sample air exiting the nasal cavities during controlled flow conditions at 5,10, and 20 L/min 1.
Computational fluid dynamics (CFD) modeling to simulate nasal airflow patterns, velocity profiles, pressure distributions, wall shear stress, and turbulence characteristics in healthy subjects 2, 3, 4, 5.
Nasal nitric oxide (NO) measurement using standardized aspiration and exhalation techniques with flow rates between 45-55 mL/s 1, 6.
Magnetic resonance imaging (MRI) and CT-based reconstruction for creating three-dimensional computational models of nasal anatomy 7.
Clinical Applications Studied:
- Air conditioning capacity of the nasal mucosa under varying temperature and humidity conditions 1.
- Identification of primary ciliary dyskinesia through nasal NO screening 1, 6.
- Virtual surgery planning and clinical decision support tools 3, 5.
- Inter-individual variations in airflow patterns among healthy subjects 2, 7.
The absence of geographic information in these technical guidelines and research papers suggests that nasal airflow studies are conducted at multiple institutions across the USA, but specific locations cannot be determined from the available evidence.
