Vessel calibre and haemoglobin effects on pulse oximetry
(IOP Publishing, 2009)Despite its success as a clinical monitoring tool, pulse oximetry may be improved with respect to the need for empirical calibration and the reports of biases in readings associated with peripheral vasoconstriction and ... -
Correlated Poincare indices for measuring heart rate variability
(The Australasian College of Physical Scientists and Engineers in Medicine, 2007-12)Poincare indices are usually applied to HRV to summarise long data sets collected over 24 hrs. Many applications of HRV are interested in dynamic, short term changes (<1 min). This study uses Poincare indices published ... -
Noninvasive detection of bilirubin using pulsatile absorption.
(Australasian College Of Physical Scientists In Medicine, 2006-03)Bilirubin, the yellow substance usually responsible for neonatal jaundice, is currently monitored invasively or by observing/measuring skin colour. This paper investigates the feasibility of monitoring serum bilirubin ...
