Ultrasonic Blood Pressure Measurement On Implanted Biomedical Surfaces
Funder
National Health and Medical Research Council
Funding Amount
$170,250.00
Summary
The project would develop a prototype device reporting blood pressure on a biomedical implant surface. The device would extract data in real time from a standard ultrasound scanner that images the implant. The School of Mathematical Sciences at Monash University will be contracted to develop this ultrasound pressure sensor.
Chronotherapy Of Hypertension In Obstructive Sleep Apnoea

Summary
Obstructive Sleep Apnoea (OSA) is linked with excess cardiovascular disease, and this is partly attributed to increased high blood pressure (hypertension). Understanding how both conditions exacerbate hypertension and whether blood pressure control can be improved by altering the time that medication is taken will lead to improvements in health.
Chronotherapy For Hypertension In Obstructive Sleep Apnea

Summary
Obstructive Sleep Apnea (OSA) is a common cause of hypertension, however treatment of OSA only results in a modest improvement in blood pressure (BP) and patients who are unable to tolerate treatment must rely on pharmacotherapy to control their BP. This study will definitively establish if altering the time of taking medication can improve BP control over 24 hours. The results will conribute to the development of more targeted treatment strategies for hypertension in people with OSA.

Summary
The kidneys are supplied with a dense network of nerves. Working properly, these nerves help maintain normal filtering of the blood by the kidneys. Over-activity of the nerves going to the kidney is associated with congestive heart failure, liver cirrhosis, chronic renal failure and hypertension. We have recently made several major discoveries about these nerves. Our studies suggest, based on structural and functional evidence, that stimulation of subgroups of nerve fibers going to the kidney wi ....The kidneys are supplied with a dense network of nerves. Working properly, these nerves help maintain normal filtering of the blood by the kidneys. Over-activity of the nerves going to the kidney is associated with congestive heart failure, liver cirrhosis, chronic renal failure and hypertension. We have recently made several major discoveries about these nerves. Our studies suggest, based on structural and functional evidence, that stimulation of subgroups of nerve fibers going to the kidney will causes different effects with in the kidney . We therefore suggest that salt excretion , the control of blood flow to the kidney and the release of hormones by the kidney can be seperately regulated by the nerves. Using techinques only practise in a handful of laboratories around the world, we aim to determine to how the nerves control kidney function normally. These studies will suggest new directions in which the renal nerves may be implicated in disease.Read moreRead less
In Vivo Studies On Ventriculo-vascular Coupling And The Role Of Aortic Pressure Wave Morphology On Coronary Blood Flow

Summary
Heart disease is a leading cause of death and disability in Australia. Conditions resulting in reduced blood flow to the heart are particularly common and dangerous. Despite significant progress, we still do not understand exactly how changes in heart function and the aorta (the major artery arising from the heart) affect blood flow to the heart. This study will utilise sophisticated new techniques to look at the interactions between heart function, pressure in the aorta and coronary blood flow
