  2. 1. Non-invasive measurement of skeletal muscle blood flow using by photoplethysmography. Experimental studies on the human leg

    Author : Qiuxia Zhang; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photoplethysmography; skeletal muscle blood flow; perfusion pressure; intramuscular pressure; venous obstruction; muscle exercise; non-invasive; limb elevation; vibration exposure; hyperaemia; foot pump.;

    Abstract : 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. READ MORE

  4. 2. Articular distension in arthroscopy : an experimental study on intra- and extra-articular effects of pressure

    Author : Anders Sperber; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Arthroscopy; intra-articular pressure; in vivo measurements; knee joint capsule; tensile properties; stress-strain; multicompartmental pressures; lower leg venous blood flow; ultrasound; acromioplasty; intra-muscular pressure; fluid absorption; shoul;

    Abstract : The purpose of this thesis was to analyse the effects of various intra-articular pressures (IAP) on soft tissues and to provide guidelines for the choice of safe infusion pressures during arthroscopy. The tensile properties of the knee-joint capsule were recorded from stress-strain-relaxation tests within 170 mmHg IAP. READ MORE

  5. 3. In the hands of ohm : hemodynamic aspects in pulmonary hypertension

    Author : Erik Tossavainen; Per Lindqvist; Michael Henein; Stefan Söderberg; Peter Eriksson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kardiologi; Cardiology;

    Abstract : Congestive heart failure (CHF) is one of the most challenging diseases in terms of health care demand and mortality, in the western world. Despite major breakthroughs in the fields of diagnosis and treatment over the three last decades, the management of CHF still remains challenging. READ MORE
