Work of breathing in exercise and disease
… on developing new methods and outcomes to assess respiratory function that require little or no volitional effort on behalf of the participants being tested. Specifically to attempt to detach the behaviour of the patient from the accuracy of the test of respiratory function, resulting in …

Numerical simulation of human breathing and particle transport through a CT-based pulmonary airway geometry
Chronic respiratory illness afflicts more than a billion people worldwide. In recent years computational fluid dynamics (CFD) has been established as a paramount tool for studying treatments of respiratory illnesses. This work investigates physiologically appropriate, lobar-specific boundary …

HOST RESPONSE TO PRIMARY AND SECONDARY CORONAVIRUS EXPOSURES AND POTENTIAL GERMINAL CENTER MECHANISMS ASSOCIATED WITH PROTECTION DURING RE-EXPOSURE
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in late 2019, causing coronavirus disease 2019 (COVID-19), a disease of varying symptoms and degrees of severity. As the virus spread globally, it was clear that certain demographics of people were more likely to experience severe …

A study of lungs in Rana catesbeiana tadpoles
… the lungs and skin are both important in respiratory exchange but in somewhat different ways. Oxygen enters through the lungs whereas carbon dioxide is excreted through the skin. Oxygen intake through the skin is determined solely by physical limitation while carbon dioxide excretion may …

Endogenous atrial natriuretic factor and airway control
This thesis describes two experiments investigating the role of endogenous atrial natriuretic factor (ANF) in the modulation of airway calibre and bronchial hyperresponsiveness in humans under normal physiological conditions. Two approaches are used. One approach examines the diurnal variation of …

Exhaled nitric oxide in asthmatic airway inflammation
Measuring the level of exhaled NO (eNO) in the breath is a new method to monitor airway inflammation in asthma and may have a role in the management of asthma. The hypotheses were that eNO will reflect the degree of inflammation in chronic asthma, and will indicate how anti- inflammatory therapy …

Study of dynamics of airflow and aerosol transport and deposition in human upper airways using large-eddy simulations
This study employs a large-eddy simulation (LES) strategy to investigate airflow and aerosol dynamics in the human upper airways using a truncated SimInhale configuration. Inflow conditions include three steady inhalation flow rates (14.2, 53.2, and 71 L/min), representing quasi-laminar, moderate, …
