11. Studies on sitting pressure and buttock microcirculation : aiming at developing an alarm in the prevention of pressure ulcers in patients with spinal cord injuries
Sammanfattning : Pressure ulcers in patients with spinal cord injuries are a major problem, the prevalence in this group being reported as high as 20 – 30 percent. Most pressure ulcers develop around the pelvic girdle, and the key-contributing factor in the development of pressure ulcers is ischaemia due to longstanding pressure. LÄS MER
12. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg
Sammanfattning : The purpose of this thesis was to validate a new non-invasive photoplethysmography (PPG) method for measuring relative changes in local muscle blood flow (MBF) in the human leg. Experimental conditions expected to impede or increase local MBF were used to test responsiveness of the PPG. LÄS MER
13. High resolution laser doppler imaging for microvascular blood flow measurements
Sammanfattning : Techniques for functional assessment of blood flow dynamics in individual microvessels are likely to become tools of increasing importance, for example in the evaluation of new vasoactive drugs. Laser Doppler perfusion Imaging (LDI) is a non- contact method for visualization of spatial and temporal blood flow dynamics. LÄS MER
14. Tissue Blood Flow Responses to External Pressure Using LDF and PPG : Testing a System Developed for Pressure Ulcer Research
Sammanfattning : Background: Pressure ulcers are a problem for immobile individuals, and having pressure ulcers impact and restrict the daily and are often associated with pain. Pressure ulcers occur frequently and cause high costs for the health care system. LÄS MER
15. Ear Reconstruction. Clinical and physiological evaluations
Sammanfattning : Microtia is a congenital malformation where the auricle is not fully developed. In some cases the malformation is complete and the auricle is absent. In Sweden the incidence of microtia is about 2 per 10,000 births. LÄS MER
