Decrease of resistance to air flow with nasal strips as measured with the airflow perturbation device

BioMedical Engineering OnLine, 2004
Background Nasal strips are used by athletes, people who snore, and asthmatics to ease the burden of breathing. Although there are some published studies that demonstrate higher flow with nasal strips, none had directly measured the effect of the strips ...

Relationships among nasal resistance, age and anthropometric parameters of the nose during growth [PDF]

Rhinology Online, 2018
Background: Children generally have a higher nasal resistance than adults. Growth changes the size and different anthropometric parameters of the nose.

A five year outbreak of methicillin-susceptible Staphylococcus aureus phage type 53,85 in a regional neonatal unit [PDF]

, 2000
We identified a 5-year outbreak of a methicillin-susceptible Staphylococcus aureus (MSSA) strain, affecting 202 babies on a neonatal unit, by routine weekly phage typing all S. aureus isolates.

Physical and geometric constraints explain the labyrinth-like shape of the nasal cavity

, 2017
The nasal cavity is a vital component of the respiratory system that heats and humidifies inhaled air in all vertebrates. Despite this common function, the shapes of nasal cavities vary widely across animals.

Contact transmission of influenza virus between ferrets imposes a looser bottleneck than respiratory droplet transmission allowing propagation of antiviral resistance [PDF]

, 2016
Influenza viruses cause annual seasonal epidemics and occasional pandemics. It is important to elucidate the stringency of bottlenecks during transmission to shed light on mechanisms that underlie the evolution and propagation of antigenic drift, host ...

Nasal resistance in facial palsy.

Nippon Jibiinkoka Gakkai Kaiho, 1989
The parasympathetic nerve which innervates the nasal mucosa is known to take a course along the facial nerve, geniculate ganglion, greater petrosal nerve and Vidian nerve as a preganglionic component. In the case of facial palsy with decreased lacrimation, it is proposed that the patients have a damage of the geniculate or suprageniculate lesion.

Investigation on the nasal airflow characteristics of anterior nasal cavity stenosis

Brazilian Journal of Medical and Biological Research, 2016
We used a computational fluid dynamics (CFD) model to study the inspiratory airflow profiles of patients with anterior nasal cavity stenosis who underwent curative surgery, by comparing pre- and postoperative airflow characteristics. Twenty patients with

Role of rhinomanometry in the prediction of therapeutic positive airway pressure for obstructive sleep apnea

Respiratory Research, 2020
Background This study was conducted to evaluate the relationship between nasal resistance in different posture and optimal positive airway pressure (PAP) level. Other potential factors were also assessed for possible influence on PAP pressure.
