Summary
Obstructive sleep apnoea has variable causes and clinical effects in different patient groups. My research will quantify the contribution of various physiological processes to the development of upper airway obstruction in different sub-types of sleep apnoea and to determine how this affects clinical presentation. I will be measuring a number of physiological parameters, and finding out how sleep apnoea manifests in terms of symptomatology and adverse health effects.
The Role Of Lung Volume In The Pathogenesis And Treatment Of Obstructive Sleep Apnea.

Summary
Obstructive sleep apnea (OSA) is a common disorder of repetitive upper airway collapse during sleep. Reducing the volume of air in the lungs increases airway collapsibility. Lung volume is therefore likely important in OSA but has not been investigated thoroughly. Also, whether raising lung volume during sleep can be used to treat OSA is unknown. The aim of this grant is therefore to investigate the role, and therapeutic potential, of lung volume in OSA.
Novel Therapeutic Phenotyping For Sleep Apnoea - A Paradoxical Role For Sedatives

Summary
Sleeping pill (sedative) use has risen dramatically. Sedatives may worsen a common breathing condition called obstructive sleep apnoea (OSA). Accordingly, their use has been discouraged in OSA. However, recent studies indicate that certain sedatives may actually reduce OSA severity in some patients. By studying the effects of common sedatives on OSA and breathing, this proposal aims to explain these apparent paradoxical responses and ultimately provide a new treatment approach for OSA.
The Role Of Sedatives And Arousal In Obstructive Sleep Apnoea – Pathophysiology And Therapeutic Utility

Summary
Recent studies indicate that certain sleeping pills (sedatives) may actually reduce obstructive sleep apnoea (OSA) severity in some patients. This research aims to determine the: 1) characteristics of patients who are most likely to respond to this novel approach. 2) effects of commonly prescribed sedatives on upper airway function and breathing during sleep. 3) utility for a sedative to yield sustained reductions in OSA severity and daytime sleepiness in the appropriately selected OSA patients.
Respiratory Phenotyping For New Targeted Approaches To Treat Sleep Apnoea

Summary
>9% of Australians have obstructive sleep apnoea (OSA). OSA has several causes. Untreated OSA is associated with major health consequences. <50% of OSA patients tolerate the main therapy, continuous positive airway pressure. New treatments are urgently required. This proposal aims to use & develop novel approaches to identify the causes of OSA on a per patient basis, improve current therapies & test if new targeted therapies can be used to treat OSA in appropriately selected patients.

Summary
The obstructive sleep apnoea hypopnoea syndrome (OSAHS) refers to a condition in which throat blockage occurs during sleep leading to breathing difficulties, including cessation of breathing for short periods of time. OSAHS affects both men and women but is amongst the commonest of chronic disorders of adult males, occurring in ~4% of men over the age of 45 years. In the proposed studies we will develop a computer model of the function of the throat during breathing.

OSAHS affects both men and women but is amongst the commonest of chronic disorders of adult males, occurring in ~4% of men over the age of 45 years. In the proposed studies we will develop a computer model of the function of the throat during breathing. A particular focus of our model will be the influence of the properties of the tissue that form the walls of the throat. Our goal is to construct a computer model that will be useful in identifying specific features of throat function that make people susceptble to the development of OSAHS. In this manner we hope to provide a tool that can be used to develop new approaches to the treatment and prevention of OSAHS.Read moreRead less
