Physiological Measurement Systems And Methods

Expertise of our group members cover the major aspects of research and development of non-invasive physiological measurement systems, including electronics design, linear and nonlinear signal processing, statistical analysis, as well as, clinical test planning and product commercialization.

We are open to collaborations to develop new diagnostic and monitoring methods, including outpatient measurements as well. Our group continuously, intensively and productively co-operates with several Departments of Tampere University Hospital.

Our main interest is to develop more accurate and well-aimed non-invasive measurements and analysis methods for the detection of cardiopulmonary diseases and assessment of wound status. The utilization is intended for hospitals and health centers, but also for outpatients.

The aim in the outpatient studies has been to evaluate changes in physiological and psychological effects arising from specific interventions. The most applied measurement modalities are based on, but not limited to, electrical and bioimpedance techniques.

We have developed a novel parameter, the ST/HR hysteresis, for the detection of ischemia during the clinical exercise test. The ST/HR hysteresis is implemented on exercise ECG workstation (CardioSoft" Diagnostic System), manufactured by the market leader GE Healthcare.

We have also developed a novel impedance pneumography method, which provides new opportunities to evaluate respiratory symptoms and diseases, especially with children and infants. The Finnish healthcare company Revenio has commercialized device and method (Ventica® System) for evaluation of asthma.

Currently we are developing a quantitative method for assessment and monitoring of chronic wound healing.
