1. Pulse oximetry : methodological considerations : experimental, in vitro and human investigations
Abstract : Pulse oximeters monitor non-invasively the haemoglobin oxygen saturation. Light of two specific wavelengths, red and infrared light, is shined through a tissue, usually the finger, and the intensity of the light transmitted is measured. Oxyhaemoglobin absorbs the light differently when compared to reduced haemoglobin. READ MORE

2. Pulse oximetry: Evaluation of a potential tool for early detection of critical congenital heart disease
Abstract : Background: About one third of newborns with life-threatening congenital heart disease leave newborn nurseries without the problem being recognized, and risk death or serious damage from circulatory collapse. The main aim of this thesis has been to evaluate if routine newborn screening with pulse oximetry could improve early in-hospital detection of newborns with duct-dependent circulation (DDC).

3. Signal Modeling and Detection in Nephrologic and Cardiac Applications
Abstract : This doctoral thesis is comprised of five parts in the field of biomedical signal processing with focus on methods for use in hemodialysis as well as in cardiac applications. The problem of predicting hypotension is the main concern in the parts were data from patients undergoing hemodialysis are used. READ MORE

4. Monitoring of Splanchnic Regional Perfusion : An Experimental Study of New Application and Validation
Abstract : Systemic infection, major surgery, trauma and many other causes can lead to impaired organ function. Compensated shock is not detected by global hemodynamic and oxygen measurements, as they take no account for regional variations. READ MORE

5. Photoplethysmography : methodological studies and applications
Abstract : Photoplethysmography (PPG), an optical non-invasive technique for measuring skin perfusion changes, was investigated and evaluated. The method was compared with laser Doppler flowmetry (LDF) when measuring perfusion changes in human fingers and forearms. READ MORE
