Nasal airflow resistance: a survey of 2500 assessments

American Journal of Rhinology

Abstract

Examination of rhinomanometric records of 2500 referred adult patients revealed 891 unobstructed noses (Rn < 0.25 Pa/cm3/sec). Topical decongestant reduced respiratory airflow resistances of these noses by 1/3 on average indicating the extent of the vascular component. Alar retraction, which minimizes resistance of the compliant portion of the nose, reduced unilateral nasal resistances by as much as 2/3, establishing the alar lumen as a major resistive segment of the unobstructed nasal airway. The nasal resistances that persisted after decongestion and alar retraction predominated in the immediately adjacent cavum. There remained 1350 noses designated as obstructed by clinician assessment of the records and suitable for analysis. Application of topical decongestant, which minimized the mucovascular component of resistance, revealed 4/5 of residual obstructions to be principally unilateral and were designated as structural. Half these structural obstructions were restricted to the alar lumen and half included the alar lumen and the adjoining cavum. Obstructions confined to the cavum were less than 2%. A further 1/5 of the nasal obstructions were bilateral and their resistances, which were markedly elevated in many cases, were su...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
