A Nasal Resistance Measurement System Based on Multi-Sensor Fusion of Pressure and Flow [PDF]

open access: yesMicromachines
Nasal obstruction is a common symptom of nasal conditions, with nasal resistance being a crucial physiological indicator for assessing severity. However, traditional rhinomanometry faces challenges with interference, limited automation, and unstable ...

Assessment of nasal resistance using computational fluid dynamics

open access: yesCurrent Directions in Biomedical Engineering, 2016
Anterior rhinomanometry is the current gold standard for the objective assessment of nasal breathing by determining the nasal resistance. However, computational fluid dynamics would allow spatially and temporally well- resolved investigation of ...

The effects of heated humidification to nasopharynx on nasal resistance and breathing pattern. [PDF]

open access: yesPLoS ONE, 2019
BACKGROUND:Mouth breathing could induce not only dry throat and eventually upper respiratory tract infection, but also snoring and obstructive sleep apnea, while nasal breathing is protective against those problems.

Effects of exercise on nasal resistance and nasal blood flow

open access: yesActa Oto-Laryngologica, 1987
Nasal resistance and nasal blood flow were measured consecutively before exercise, immediately after exercise, 5, 10, 15, 20, 25, and 30 minutes after exercise in 11 normal subjects and 18 patients with perennial allergic rhinitis. Nasal resistance was measured by Nihon-Koden Rhinorheograph MRP 2100, and nasal blood flow was measured by Periflux PF2, a

Effect of Dupilumab on Sleep Apnea Severity in Patients With Chronic Rhinosinusitis [PDF]

open access: yesSleep Medicine Research, 2023
Patients with chronic rhinosinusitis (CRS) report improved sleep quality after dupilumab, an anti IL4/13 therapy. Concurrent CRS and obstructive sleep apnea (OSA) cases are not rare, and CRS seemingly raises nasal resistance.

Rapid Maxillary Expansion Has a Beneficial Effect on the Ventilation in Children With Nasal Septal Deviation: A Computational Fluid Dynamics Study

open access: yesFrontiers in Pediatrics, 2022
Nasal septal deviation (NSD) is one of the most common nasal diseases. Different from common clinical examination methods, computational fluid dynamics (CFD) can provide visual flow information of the nasal cavity.
