  1. 1. Skin conductance variability and stressful exposures in critical care

    Författare :Anders Günther; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Numerous stressors affect the intensive care unit (ICU) patient. The ICU environment is busy and noisy, with monitoring and treatment around the clock. ICU patients may have problems in getting some sleep, due to lighting and noise. Many ICU survivors report having pain during their ICU stay. LÄS MER

  3. 2. Physiological Stress Reactivity in Late Pregnancy

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acoustic startle response; allopregnanolone; antenatal; anxiety; cold pressor test; cortisol; cortisol awakening response; depression; electrodermal; estradiol; hypothalamic-pituitary-adrenal axis; postpartum; pregnancy; progesterone; skin conductance; stress; sympathetic nervous system; Medical Science; Medicinsk vetenskap;

    Sammanfattning : During pregnancy, the basal activity is increased in both of our major stress response systems: the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis. At the same time, the reactivity towards stressors is reduced. These alterations sustain maternal and fetal homeostasis, and are involved in the regulation of gestational length. LÄS MER

  4. 3. Guided by Fear : Effects on attention and awareness

    Författare :Nathalie Peira; Stefan Wiens; Nazanin Derakhshan; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Emotion; fear; attention; awareness; affective processing; heart rate; skin conductance; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Because the visual system has limited capacity, emotions such as fear may play an important role in guiding the selection of relevant input (LeDoux, 2000; Öhman & Mineka, 2001). The aim of the current thesis was to investigate how fear can guide the organism by influencing:  (I) attentional processes, (II) awareness of the visual input, and (III) affective processing independent of awareness.

  5. 4. Studies on skin blood flow and evaporative water loss : a bioengineering approach

    Författare :Lena Nilsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Skin blood flow (SBF), temperature, evaporative water loss (EWL) and skin conductance (SC) measured during stimulus-response experiments reveal valuable information regarding the skin's regulatory capacity. SBF and EWL play powerful roles in keeping the human body within an adequate temperature range. LÄS MER

  7. 5. Multi-Sensor Data Synchronization using Mobile Phones

    Författare :Jonas Wåhslén; Thomas Lindh; Jens Eliason; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless body sensor networks; wireless personal area network; sport technology; Bluetooth performance; time synchronization; data fusion; mobile phone application.;

    Sammanfattning : Body sensor networking is a rapidly growing technology. Today wearable sensors are used to measure and monitor e.g. pulse, temperature, skin conductance, heart activity, and movement (through GPS or inertial measurement units). LÄS MER
