  1. 1. Sensor-Based Garments that Enable the Use of Bioimpedance Technology : Towards PersonalizedHealthcare Monitoring

    Författare :Juan Carlos Marquez Ruiz; Kaj Lindecrantz; Fernando Seoane; Ramon Bragós Bardia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioimpedance; textrodes; textile electrodes; Impedance Cardiography; Body Composition;

    Sammanfattning : Functional garments for physiological sensing purposes have been utilized in several disciplinesi.e. sports, firefighting, military and medical. In most of the cases textile electrodes (Textrodes)embedded in the garment are employed to monitor vital signs and other physiologicalmeasurements. LÄS MER

  4. 3. Cardiac Resynchronization Therapy Optimization : Comparison and Evaluation of Non-invasive Methods

    Författare :Elena Sciaraffia; Carina Blomström Lundqvist; Giuseppe Boriani; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac resynchronization therapy; device optimization; left ventricular contractility; Cardiology; Kardiologi;

    Sammanfattning : The general purpose of this thesis was to investigate new cardiac resynchronization therapy (CRT) optimization techniques and to assess their reliability when compared to invasive measurements of left ventricular contractility (LV dP/dtmax).We first assessed whether cardiac output (CO) measured by trans-thoracic impedance cardiography could correctly identify the optimal interventricular (VV) pacing interval while using invasive measurements of LV dP/dtmax as reference.

  5. 4. Sympathetic neural blockade during regional analgesia : Clinical investigations in man

    Författare :Lars-Åke Malmqvist; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Different opinions exist concerning the extent and intensi-ty of the concomitant sympathetic block during regional blockade, and how to test the completeness of the sympathetic blockade. Studies were performed on 21 volunteers and 162 patients scheduled for surgery of the urogenital area or surgery for varicose v-eins, and chronic pain patients. LÄS MER

  7. 5. Cardiovascular response to hyperoxemia, hemodilution and burns : a clinical and experimental study

    Författare :Zoltan Bak; Birgitta Janerot Sjöberg; Robert Hahn; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anesthesia; general; Burns; Echocardiography; transesophageal; Hemodilution; emodynamic processes; Hyperoxia; Intensive care; Intensivvård;

    Sammanfattning : The last decades less invasive monitoring and analytical tools have been developed for the evaluation of myocardial mechanics in clinical praxis. In critical care, these are longed-for complements to pulmonary artery catheter monitoring, additionally offering previously inaccessible information. LÄS MER
