Regulation Of Pulmonary Responsiveness By Chronic Mechanical Strain And Its Role In Obstructive Lung Disease

Funding Amount

Summary
The pressures required to breathe place a continuous but varying mechanical strain on airway passages and lung tissue. This mechanical strain may protect the airway from collapsing, however, this protection is deficient in lung diseases such as asthma. This project considers the possibility that abnormal mechanical strain occurring in lung disease predisposes the individual to debilitating and potentially life-threatening airflow obstruction.
A Novel Optical Stimulation Method For Obstructive Sleep Apnoea Treatment

Funding Amount
$510,913.00
Summary
This project aims to develop and characterize a novel optogenetic pharyngeal stimulation system to dilate the upper airway using a light stimulus. This will provide proof-of-concept for a new minimally invasive treatment option for obstructive sleep apnoea.
Chronic obstructive pulmonary disease (COPD) causes airway narrowing and lung destruction resulting in breathlessness and cough. Earlier detection of acute attacks of breathlessness may improve treatment, prevent progression and reduce risk of death. The forced oscillation technique can detect attacks earlier and is easy to perform. It will be used in this study for home monitoring with application of time series analyses to accurately detect change so that acute attacks can be treated earlier.
Defining Regional Lung Mechanics To Improve Lung Protective Ventilation Strategies In Newborn Infants

Funding Amount

Summary
Over 3000 newly born infants require mechanical ventilation in Australia every year. The majority are very premature infants. About 30% of ventilated infants develop serious ventilator induced lung injury. Minimising such lung injury with improved techniques of ventilation which can protect the lung from injury will reduce the considerable short and long term health burden of this population.
Translation Of Abdominal Functional Electrical Stimulation From A Research Tool To Clinical Practice

Funding Amount
$318,768.00
Summary
People with a spinal cord injury to the neck are often unable to move their arms and legs, a condition known as tetraplegia. Tetraplegics are also unable to use their abdominal muscles, reducing breathing and bowel function. This project will use electrical pulses to make their abdominal muscles contract, improving breathing and bowel function. The results will be used to develop a program that can be used in all hospitals, reducing illness in tetraplegia and saving the health service money.
The Western Australia Malignant Pleural Effusions Management Study- What Factors Can Guide Management And Do Indwelling Pleural Catheters Represent The Best Treatment Option?
Funder
National Health and Medical Research Council
Funding Amount
$74,395.00
Summary
This randomised clinical trial will determine whether indwelling tunnelled pleural catheters are the best treatment strategy for patients with malignant pleural effusions. It will also look for ways in which the speed of fluid recurrence can be predicted. It will save public money by finding the most cost effective treatment strategies.
Non-invasive Methods Of Measuring Work Of Breathing In Children

Summary
Sleep-disordered breathing such as obstructive sleep apnoea, is currently diagnosed if a child stops breathing more than once per hour. For children with asthma or cystic fibrosis, who may not stop breathing during the night, how hard their breathing muscles work can have a significant impact on their health. A non-invasive method of measuring respiratory effort, and incorporating this measurement into how sleep-disordered breathing is diagnosed, can revolutionize how sleep-disordered breathing ....Sleep-disordered breathing such as obstructive sleep apnoea, is currently diagnosed if a child stops breathing more than once per hour.

The uneven way that airways narrow (heterogeneity) would seem to be an important factor affecting the natural history, clinical expression and response to treatment in patients with severe asthma. In this study we will be looking at the mechanism for heterogeneity in sufferers of severe asthma in relation to how stiff the lung is and the type of inflammation seen in these patients.
Risk Assessment And Prevention Of Respiratory Complications In Paediatric Anaesthesia

Funding Amount
$494,253.00
Summary
Respiratory problems account for more than three quarters of all critical incidents and a third of all cardiac arrests in healthy children undergoing anaesthesia for surgical procedures. It is therefore vital to identify high risk children early to be able to adapt the anaesthesia regimen accordingly. This series of studies will study new prediction and prevention strategies to minimise respiratory problems and therefore improve the safety for our children when undergoing anaesthesia.
